21 lftp is a file transfer program that allows sophisticated FTP, HTTP and
22 other connections to other hosts. If site is specified then lftp will
23 connect to that site otherwise a connection has to be established with
24 the open command.
25 lftp can handle several file access methods - FTP, FTPS, HTTP, HTTPS,
27 HFTP, FISH, SFTP and file (HTTPS and FTPS are only available when lftp
28 is compiled with GNU TLS or OpenSSL library). You can specify the
29 method to use in `open URL' command, e.g. `open http://www.us.ker‐
30 nel.org/pub/linux'. HFTP is ftp-over-http-proxy protocol. It can be
31 used automatically instead of FTP if ftp:proxy is set to
32 `http://proxy[:port]'. Fish is a protocol working over an ssh connec‐
33 tion to a unix account. SFtp is a protocol implemented in SSH2 as SFTP
34 subsystem.
35 Besides FTP-like protocols, lftp has support for BitTorrent protocol as
37 `torrent' command. Seeding is also supported.
38 Every operation in lftp is reliable, that is any non-fatal error is
41 handled properly and the operation is repeated. So if downloading
42 breaks, it will be restarted from the point automatically. Even if FTP
43 server does not support the REST command, lftp will try to retrieve the
44 file from the very beginning until the file is transferred completely.
45 lftp has shell-like command syntax allowing you to launch several com‐
47 mands in parallel in background (&). It is also possible to group com‐
48 mands within () and execute them in background. All background jobs are
49 executed in the same single process. You can bring a foreground job to
50 background with ^Z (c-z) and back with command `wait' (or `fg' which is
51 alias to `wait'). To list running jobs, use command `jobs'. Some com‐
52 mands allow redirecting their output (cat, ls, ...) to file or via pipe
53 to external command. Commands can be executed conditionally based on
54 termination status of previous command (&&, ||).
55 If you exit lftp before all jobs are not finished yet, lftp will move
57 itself to nohup mode in background. The same thing happens with a real
58 modem hangup or when you close an xterm.
59 lftp has built-in mirror which can download or update a whole directory
61 tree. There is also reverse mirror (mirror -R) which uploads or updates
62 a directory tree on server. Mirror can also synchronize directories
63 between two remote servers, using FXP if available.
64 There is command `at' to launch a job at specified time in current con‐
66 text, command `queue' to queue commands for sequential execution for
67 current server, and much more.
68 On startup, lftp executes /etc/lftp.conf and then ~/.lftprc and
70 ~/.lftp/rc (or ~/.config/lftp/rc if ~/.lftp does not exist). You can
71 place aliases and `set' commands there. Some people prefer to see full
72 protocol debug, use `debug' to turn the debug on. Use `debug 3' to see
73 only greeting messages and error messages.
74 lftp has a number of settable variables. You can use `set -a' to see
76 all variables and their values or `set -d' to see list of defaults.
77 Variable names can be abbreviated and prefix can be omitted unless the
78 rest becomes ambiguous.
79 If lftp was compiled with OpenSSL (configure --with-openssl) it
81 includes software developed by the OpenSSL Project for use in the
82 OpenSSL Toolkit. (http://www.openssl.org/)
83 Commands
86 ! shell command
87 Launch shell or shell command.
89 !ls
91 To do a directory listing of the local host.
93 alias [name [value]]
95 Define or undefine alias name. If value is omitted, the alias is unde‐
97 fined, else it takes the value value. If no argument is given the cur‐
98 rent aliases are listed.
99 alias dir ls -lF
101 alias less zmore
102 at time [ -- command ]
104 Wait until the given time and execute given (optional) command. See
106 also at(1).
107 attach [PID]
109 Attach the terminal to specified backgrounded lftp process.
111 bookmark [subcommand]
113 The bookmark command controls bookmarks.
115 Site names can be used in the open command directly as-is or in any
117 command that accepts input URLs using the bm:site/path format.
118 add <name> [<loc>] add current place or given location to
120 bookmarks and bind to given name
121 del <name> remove bookmark with name
122 edit start editor on bookmarks file
123 import <type> import foreign bookmarks
124 list list bookmarks (default)
125 cache [subcommand]
127 The cache command controls local memory cache. The following subcom‐
129 mands are recognized:
130 stat print cache status (default)
132 on|off turn on/off caching
134 flush flush cache
135 size lim set memory limit, -1 means unlimited
136 expire Nx set cache expiration time to N seconds (x=s) minutes (x=m)
137 hours (x=h) or days (x=d)
138 cat files
140 cat outputs the remote file(s) to stdout. (See also more, zcat and
142 zmore)
143 cd rdir
145 Change current remote directory. The previous remote directory is
147 stored as `-'. You can do `cd -' to change the directory back. The
148 previous directory for each site is also stored on disk, so you can do
149 `open site; cd -' even after lftp restart.
150 chmod [OPTS] mode files...
152 Change permission mask on remote files. The mode can be an octal number
154 or a symbolic mode (see chmod(1)).
155 -c, --changes like verbose but report only when a change is made
157 -f, --quiet suppress most error messages
158 -v, --verbose output a diagnostic for every file processed
159 -R, --recursive change files and directories recursively
160 close [-a]
162 Close idle connections. By default only with the current server, use
164 -a to close all idle connections.
165 cls [OPTS] files...
167 `cls' tries to retrieve information about specified files or directo‐
169 ries and outputs the information according to format options. The dif‐
170 ference between `ls' and `cls' is that `ls' requests the server to for‐
171 mat file listing, and `cls' formats it itself, after retrieving all the
172 needed information.
173 -1 single-column output
175 -a, --all show dot files
176 -B, --basename show basename of files only
177 --block-size=SIZ use SIZ-byte blocks

191 files
192 -i, --nocase case-insensitive pattern matching
193 -I, --sortnocase sort names case-insensitively
194 -D, --dirsfirst list directories first
195 --sort=OPT "name", "size", "date"
196 -S sort by file size

198 --perms, --date,
200 --linkcount, --links show individual fields
201 --time-style=STYLE use specified time format
202 command cmd args...
204 execute given command ignoring aliases.
206 debug [OPTS] level|off
208 Switch debugging to level or turn it off. Options:
210 -T truncate output file
212 -o <file> redirect debug output to the file
213 -c show message context
214 -p show PID
215 -t show timestamps
216 du [OPTS] path...
218 Summarize disk usage. Options:
220 -a, --all write counts for all files, not just
222 directories
223 --block-size=SIZ use SIZ-byte blocks
224 -b, --bytes print size in bytes
225 -c, --total produce a grand total
226 -d, --max-depth=N print the total for a directory (or file,
227 with --all) only if it is N or fewer lev‐
228 els below the command line argument;
229 --max-depth=0 is the same as --summarize
230 -F, --files print number of files instead of sizes
231 -h, --human-readable print sizes in human readable format
232 (e.g., 1K 234M 2G)
233 -H, --si likewise, but use powers of 1000 not 1024
234 -k, --kilobytes like --block-size=1024
235 -m, --megabytes like --block-size=1048576
236 -S, --separate-dirs do not include size of subdirectories
237 -s, --summarize display only a total for each argument
238 --exclude=PAT exclude files that match PAT
239 echo [-n] string
241 Prints (echos) the given string to the display.
243 edit [OPTS] file
245 Retrieve remote file to a temporary location, run a local editor on it
247 and upload the file back if changed. Options:
248 -k keep the temporary file
250 -o <temp> explicit temporary file location
251 eval [-f format ] args...
253 without -f it executes given arguments as a command. With -f, arguments
255 are transformed into a new command. The format can contain plain text
256 and placeholders $0...$9 and $@, corresponding to the arguments.
257 exit [bg] [top] [parent] [kill] [code]
259 exit will exit from lftp or move to background if there are active
261 jobs. If no job is active, code is passed to operating system as lftp's
262 termination status. If code is omitted, the exit code of last command
263 is used.
264 `exit bg' forces moving to background when cmd:move-background is
266 false. `exit top' makes top level `shell' (internal lftp command
267 executor) terminate. `exit parent' terminates the parent shell when
268 running a nested script. `exit kill' kills all numbered jobs before
269 exiting. The options can be combined, e.g. `at 08:00 -- exit top kill
270 &' kills all jobs and makes lftp exit at specified time.
271 fg
273 Alias for `wait'.
275 find [OPTS] directory...
277 List files in the directory (current directory by default) recursively.
279 This can help with servers lacking ls -R support. You can redirect out‐
280 put of this command. Options:
281 -d MD, --max-depth=MD specify maximum scan depth
283 -l, --ls use long listing format
284 ftpcopy
286 Obsolete. Use one of the following instead:
288 get ftp://... -o ftp://...
289 get -O ftp://... file1 file2...
290 put ftp://...
291 mput ftp://.../*
292 mget -O ftp://... ftp://.../*
293 or other combinations to get FXP transfer (directly between two FTP
294 servers). lftp would fallback to plain copy (via client) if FXP trans‐
295 fer cannot be initiated or ftp:use-fxp is false.
296 get [-E] [-a] [-c] [-e] [-P N] [-O base] rfile [-o lfile] ...
298 Retrieve the remote file rfile and store it as the local file lfile.
300 If -o is omitted, the file is stored to local file named as base name
301 of rfile. You can get multiple files by specifying multiple instances
302 of rfile (and -o lfile). Does not expand wildcards, use mget for that.
303 -c continue, reget
305 -E delete source files after successful transfer
306 -e delete target file before the transfer
307 -a use ascii mode (binary is the default)
308 -P N download N files in parallel
309 -O <base> specifies base directory or URL where files should
310 be placed
311 Examples:
313 get README
314 get README -o debian.README
315 get README README.mirrors
316 get README -o debian.README README.mirrors -o debian.mirrors
317 get README -o ftp://some.host.org/debian.README
318 get README -o ftp://some.host.org/debian-dir/ (end slash is important)
319 get1 [OPTS] rfile
321 Transfer a single file. Options:
323 -o <lfile> destination file name (default - base‐
325 name of rfile)
326 -c continue, reget
327 -E delete source files after successful
328 transfer
329 -a use ascii mode (binary is the default)
330 -d create the directory of the target file
332 --source-region=<from-to> transfer specified region of source
333 file
334 --target-position=<pos> position in target file to write data
335 at
336 glob [OPTS] [command] patterns
338 Glob given patterns containing metacharacters and pass result to given
340 command or return appropriate exit code.
341 -f plain files (default)
343 -d directories
344 -a all types
345 --exist return zero exit code when the patterns expand to non-empty list
346 --not-exist return zero exit code when the patterns expand to an empty list
347 Examples:
349 glob echo *
350 glob --exist *.csv && echo "There are *.csv files"
351 help [cmd]
353 Print help for cmd or if no cmd was specified print a list of available
355 commands.
356 history [OPTS] [cnt]
358 View or manipulate the command history. Optional argument cnt speci‐
360 fies the number of history lines to list, or "all" to list all entries.
361 Options:
362 -w <file> Write history to file.
364 -r <file> Read history from file; appends to current history.
365 -c Clear the history.
366 -l List the history (default).
367 jobs [OPTS] [job_no...]
369 List running jobs. If job_no is specified, only list a job with that
371 number. Options:
372 -v verbose, several -v increase verbosity
374 -r list just one specified job without recursion
375 kill all|job_no
377 Delete specified job with job_no or all jobs. (For job_no see jobs)
379 lcd ldir
381 Change current local directory ldir. The previous local directory is
383 stored as `-'. You can do `lcd -' to change the directory back.
384 ln [-s] existing-file new-link
386 Make a hard/symbolic link to an existing file. Option -s selects cre‐
388 ation of a symbolic link.
389 local command
391 Run specified command with local directory file:// session instead of
393 remote session. Examples:
394 local pwd
395 local ls
396 local mirror /dir1 /dir2
397 lpwd
399 Print current working directory on local machine.
401 ls params
403 List remote files. You can redirect output of this command to file or
405 via pipe to external command. By default, ls output is cached, to see
406 new listing use rels or cache flush.
407 mget [-c] [-d] [-a] [-E] [-e] [-P N] [-O base] files
409 Gets selected files with expanded wildcards.
411 -c continue, reget.
413 -d create directories the same as file names and get
414 the files into them instead of current directory.
415 -E delete source files after successful transfer
416 -e delete target file before the transfer
417 -a use ascii mode (binary is the default)
418 -P N download N files in parallel
419 -O <base> specifies base directory or URL where files should
420 be placed
421 mirror [OPTS] [source [target]]
423 Mirror specified source directory to the target directory.
425 By default the source is remote and the target is a local directory.
427 When using -R, the source directory is local and the target is remote.
428 If the target directory is omitted, base name of the source directory
429 is used. If both directories are omitted, current local and remote
430 directories are used.
431 The source and/or the target may be URLs pointing to directories.
433 If the target directory ends with a slash (except the root directory)
435 then base name of the source directory is appended.
436 -c, --continue continue a mirror job if
438 possible
439 -e, --delete delete files not present at
440 the source
441 --delete-excluded delete files excluded at the
442 target
443 --delete-first delete old files before
444 transferring new ones
445 --depth-first descend into subdirectories
446 before transferring files
447 --scan-all-first scan all directories recur‐
448 sively before transferring
449 files
450 -s, --allow-suid set suid/sgid bits according
451 to the source
452 --allow-chown try to set owner and group
453 on files
454 --ascii use ascii mode transfers
455 (implies --ignore-size)
456 --ignore-time ignore time when deciding
457 whether to download
458 --ignore-size ignore size when deciding
459 whether to download
460 --only-missing download only missing files

466 (-c won't work)
467 --upload-older upload even files older than
468 the target ones
469 --transfer-all transfer all files, even
470 seemingly the same at the
471 target site
472 --no-empty-dirs don't create empty directo‐
473 ries (implies --depth-first)
474 -r, --no-recursion don't go to subdirectories
475 --recursion=MODE go to subdirectories on a
476 condition
477 --no-symlinks don't create symbolic links
478 -p, --no-perms don't set file permissions
479 --no-umask don't apply umask to file
480 modes
481 -R, --reverse reverse mirror (put files)
482 -L, --dereference download symbolic links as
483 files
484 --overwrite overwrite plain files with‐
485 out removing them first
486 --no-overwrite remove and re-create plain
487 files instead of overwriting
488 -N, --newer-than=SPEC download only files newer
489 than specified time
490 --older-than=SPEC download only files older
491 than specified time
492 --size-range=RANGE download only files with
493 size in specified range
494 -P, --parallel[=N] download N files in parallel
495 --use-pget[-n=N] use pget to transfer every
496 single file
497 --on-change=CMD execute the command if any‐
498 thing has been changed
499 --loop repeat mirror until no
500 changes found
501 -i RX, --include=RX include matching files
502 -x RX, --exclude=RX exclude matching files
503 -I GP, --include-glob=GP include matching files
504 -X GP, --exclude-glob=GP exclude matching files
505 --include-rx-from=FILE
506 --exclude-rx-from=FILE
507 --include-glob-from=FILE
508 --exclude-glob-from=FILE load include/exclude pat‐
509 terns from the file, one per
510 line
511 -f FILE, --file=FILE mirror a single file or
512 globbed group (e.g.
513 /path/to/*.txt)
514 -F DIR, --directory=DIR mirror a single directory or
515 globbed group (e.g.
516 /path/to/dir*)
517 -O DIR, --target-directory=DIR target base path or URL
518 -v, --verbose[=level] verbose operation
519 --log=FILE write lftp commands being
520 executed to FILE
521 --script=FILE write lftp commands to FILE,
522 but don't execute them
523 --just-print, --dry-run same as --script=-
524 --max-errors=N stop after this number of
525 errors
526 --skip-noaccess don't try to transfer files
527 with no read access.
528 --use-cache use cached directory list‐
530 ings
531 --Remove-source-files remove source files after
532 transfer (use with caution)
533 --Remove-source-dirs remove source files and
534 directories after transfer
535 (use with caution). Top
536 level directory is not
537 removed if it's name ends
538 with a slash.
539 --Move same as --Remove-source-dirs
540 -a same as --allow-chown
541 --allow-suid --no-umask
542 RX is an extended regular expression, just like in egrep(1).
543 GP is a glob pattern, e.g. `*.zip'.
545 Include and exclude options can be specified multiple times. It means
547 that a file or directory would be mirrored if it matches an include and
548 does not match to excludes after the include, or does not match any‐
549 thing and the first check is exclude. Directories are matched with a
550 slash appended.
551 Note that symbolic links are not created when uploading to remote
553 server, because FTP protocol cannot do it. To upload files the links
554 refer to, use `mirror -RL' command (treat symbolic links as files).
555 For options --newer-than and --older-than you can either specify a file
557 or time specification like that used by at(1) command, e.g.
558 `now-7days' or `week ago'. If you specify a file, then modification
559 time of that file will be used.
560 Verbosity level can be selected using --verbose=level option or by sev‐
562 eral -v options, e.g. -vvv. Levels are:
563 0 - no output (default)
564 1 - print actions
565 2 - +print not deleted file names (when -e is not specified)
566 3 - +print directory names which are mirrored
567 --only-newer turns off file size comparison and uploads/downloads only
569 newer files even if size is different. By default older files are
570 transferred and replace newer ones.
571 --upload-older allows replacing newer remote files with older ones
573 (when the target side is remote). Some remote back-ends cannot preserve
574 timestamps so the default is to keep newer files.
575 Recursion mode can be one of `always', `never', `missing', `newer'.
577 With the option `newer' mirror compares timestamps of directories and
578 enters a directory only if it is older or missing on the target side.
579 Be aware that when a file changes the directory timestamp may stay the
580 same, so mirror won't process that directory.
581 The options --file and --directory may be used multiple times and even
583 mixed provided that base directories of the paths are the same.
584 You can mirror between two servers if you specify URLs instead of
586 directories. FXP is automatically used for transfers between FTP
587 servers, if possible.
588 Some FTP servers hide dot-files by default (e.g. .htaccess), and show
590 them only when LIST command is used with -a option. In such case try to
591 use `set ftp:list-options -a'.
592 The recursion modes `newer' and `missing' conflict with
594 --scan-all-first, --depth-first, --no-empty-dirs and setting mir‐
595 ror:no-empty-dirs=true.
596 mkdir [-p] [-f] dir(s)
598 Make remote directories. If -p is used, make all components of paths.
600 The -f option makes mkdir quiet and suppresses messages.
601 module module [ args ]
603 Load given module using dlopen(3) function. If module name does not
605 contain a slash, it is searched in directories specified by module:path
606 variable. Arguments are passed to module_init function. See
607 README.modules for technical details.
608 more files
610 Same as `cat files | more'. if PAGER is set, it is used as filter.
612 (See also cat, zcat and zmore)
613 mput [-c] [-d] [-a] [-E] [-e] [-P N] [-O base] files
615 Upload files with wildcard expansion. By default it uses the base name
617 of local name as remote one. This can be changed by `-d' option.
618 -c continue, reput
620 -d create directories the same as in file names and put
621 the files into them instead of current directory
622 -E delete source files after successful transfer (dan‐
623 gerous)
624 -e delete target file before the transfer
625 -a use ascii mode (binary is the default)
626 -P N upload N files in parallel
627 -O <base> specifies base directory or URL where files should
628 be placed
629 mrm file(s)
631 Same as `glob rm'. Removes specified file(s) with wildcard expansion.
633 mmv [-O directory] file(s) directory
635 Move specified files to a target directory. The target directory can be
637 specified after -O option or as the last argument.
638 -O <dir> specifies the target directory where files should be
640 placed
641 mv file1 file2
643 Rename file1 to file2. No wildcard exmapsion is performed. If you give
645 more than two arguments, or the last argument ends with a slash, then
646 mmv command is executed instead.
647 nlist [args]
649 List remote file names
651 open [OPTS] site
653 Select a server by host name, URL or bookmark. When an URL or bookmark
655 is given, automatically change the current working directory to the
656 directory of the URL. Options:
657 -e cmd execute the command just after selecting the server
659 -u user[,pass] use the user/password for authentication
660 -p port use the port for connection
662 -s slot assign the connection to this slot
663 -d enable debug
664 -B don't look up bookmarks
665 --user user use the user for authentication
666 --password pass use the password for authentication
667 --env-password take password from LFTP_PASSWORD environment variable
668 site host name, URL or bookmark name
669 pget [OPTS] rfile [-o lfile]
671 Gets the specified file using several connections. This can speed up
673 transfer, but loads the net and server heavily impacting other users.
674 Use only if you really have to transfer the file ASAP. Options:
675 -c continue transfer. Requires lfile.lftp-pget-status
677 file.
678 -n maxconn set maximum number of connections (default is taken
679 from pget:default-n setting)
680 put [-E] [-a] [-c] [-e] [-P N] [-O base] lfile [-o rfile]
682 Upload lfile with remote name rfile. If -o omitted, the base name of
684 lfile is used as remote name. Does not expand wildcards, use mput for
685 that.
686 -o <rfile> specifies remote file name (default - basename of
688 lfile)
689 -c continue, reput. It requires permission to over‐
690 write remote files
691 -E delete source files after successful transfer (dan‐
692 gerous)
693 -e delete target file before the transfer
694 -a use ascii mode (binary is the default)
695 -P N upload N files in parallel
696 -O <base> specifies base directory or URL where files should
697 be placed
698 pwd [-p]
700 Print current remote URL. Use `-p' option to show password in the URL.
702 queue [-n num ] cmd
704 Add the given command to queue for sequential execution. Each site has
706 its own queue. `-n' adds the command before the given item in the
707 queue. Don't try to queue `cd' or `lcd' commands, it may confuse lftp.
708 Instead do the cd/lcd before `queue' command, and it will remember the
709 place in which the command is to be done. It is possible to queue up an
710 already running job by `queue wait <jobno>', but the job will continue
711 execution even if it is not the first in queue.
712 `queue stop' will stop the queue, it will not execute any new commands,
714 but already running jobs will continue to run. You can use `queue stop'
715 to create an empty stopped queue. `queue start' will resume queue exe‐
716 cution. When you exit lftp, it will start all stopped queues automati‐
717 cally.
718 `queue' with no arguments will either create a stopped queue or print
720 queue status.
721 queue --delete|-d [index or wildcard expression]
723 Delete one or more items from the queue. If no argument is given, the
725 last entry in the queue is deleted.
726 queue --move|-m <index or wildcard expression> [index]
728 Move the given items before the given queue index, or to the end if no
730 destination is given.
731 -q Be quiet.
733 -v Be verbose.
734 -Q Output in a format that can be used to re-queue. Useful
735 with --delete.
736 Examples:
738 > get file &
739 [1] get file
740 > queue wait 1
741 > queue get another_file
742 > cd a_directory
743 > queue get yet_another_file
744 queue -d 3 Delete the third item in the queue.
746 queue -m 6 4 Move the sixth item in the queue before
747 the fourth.
748 queue -m "get*zip" 1 Move all commands matching "get*zip" to
749 the beginning of the queue. (The order
750 of the items is preserved.)
751 queue -d "get*zip" Delete all commands matching "get*zip".
752 quote cmd
754 For FTP - send the command uninterpreted. Use with caution - it can
756 lead to unknown remote state and thus will cause reconnect. You cannot
757 be sure that any change of remote state because of quoted command is
758 solid - it can be reset by reconnect at any time.
759 For HTTP - specific to HTTP action. Syntax: ``quote <command>
761 [<args>]''. Command may be ``set-cookie'' or ``post''.
762 open http://www.site.net
763 quote set-cookie "variable=value; othervar=othervalue"
764 set http:post-content-type application/x-www-form-urlencoded
765 quote post /cgi-bin/script.cgi "var=value&othervar=othervalue" > local_file
766 For FISH - send the command uninterpreted. This can be used to execute
768 arbitrary commands on server. The command must not take input or print
769 ### at new line beginning. If it does, the protocol will become out of
770 sync.
771 open fish://server
772 quote find -name \*.zip
773 reget rfile [-o lfile]
775 Same as `get -c'.
777 rels [args]
779 Same as `ls', but ignores the cache.
781 renlist [args]
783 Same as `nlist', but ignores the cache.
785 repeat [OPTS] [[-d] delay] [command]
787 Repeat specified command with a delay between iterations. Default
789 delay is one second, default command is empty.
790 -c <count> maximum number of iterations
792 -d <delay> delay between iterations
794 --while-ok stop when command exits with non-zero code
795 --until-ok stop when command exits with zero code
796 --weak stop when lftp moves to background.
797 Examples:
799 repeat at tomorrow -- mirror
800 repeat 1d mirror
801 reput lfile [-o rfile]
803 Same as `put -c'.
805 rm [-r] [-f] files
807 Remove remote files. Does not expand wildcards, use mrm for that. -r
809 is for recursive directory remove. Be careful, if something goes wrong
810 you can lose files. -f suppress error messages.
811 rmdir dir(s)
813 Remove remote directories.
815 scache [session]
817 List cached sessions or switch to specified session.
819 set [var [val]]
821 Set variable to given value. If the value is omitted, unset the vari‐
823 able. Variable name has format ``name/closure'', where closure can
824 specify exact application of the setting. See below for details. If
825 set is called with no variable then only altered settings are listed.
826 It can be changed by options:
827 -a list all settings, including default values
829 -d list only default values, not necessary current ones
830 site site_cmd
832 Execute site command site_cmd and output the result. You can redirect
834 its output.
835 sleep interval
837 Sleep given time interval and exit. Interval is in seconds by default,
839 but can be suffixed with 'm', 'h', 'd' for minutes, hours and days
840 respectively. See also at.
841 slot [name]
843 Select specified slot or list all slots allocated. A slot is a connec‐
845 tion to a server, somewhat like a virtual console. You can create mul‐
846 tiple slots connected to different servers and switch between them. You
847 can also use slot:name as a pseudo-URL evaluating to that slot loca‐
848 tion.
849 Default readline binding allows quick switching between slots named 0-9
851 using Meta-0 - Meta-9 keys (often you can use Alt instead of Meta).
852 source file
854 source -e command
855 Execute commands recorded in file file or returned by specified exter‐
857 nal command.
858 source ~/.lftp/rc
859 source -e echo help
860 suspend
862 Stop lftp process. Note that transfers will be also stopped until you
864 continue the process with shell's fg or bg commands.
865 torrent [OPTS] torrent-files...
867 Start BitTorrent process for the given torrent-files, which can be a
869 local file, URL, magnet link or plain info_hash written in hex or
870 base32. Local wildcards are expanded. Existing files are first vali‐
871 dated unless --force-valid option is given. Missing pieces are down‐
872 loaded. Files are stored in specified directory or current working
873 directory by default. Seeding continues until ratio reaches tor‐
874 rent:stop-on-ratio setting or time of torrent:seed-max-time runs out.
875 Options:
877 -O <directory> specifies base directory where files
879 should be placed
880 --force-valid skip file validation (if you are sure
881 they are ok).
882 --only-new stop if the metadata is known already
883 or the torrent is complete.
884 --only-incomplete stop if the torrent is already com‐
885 plete.
886 --dht-bootstrap=<node> bootstrap DHT by sending a query to
887 specified node. This option should be
888 used just once to fill the local node
889 cache. Port number may be given after
890 colon, default is 6881. Here are some
891 nodes for bootstrapping: dht.transmis‐
892 sionbt.com, router.utorrent.com,
893 router.bittorrent.com.
894 --share share specified file or directory using
895 BitTorrent protocol. Magnet link is
896 printed when it's ready.
897 user user [pass]
899 user URL [pass]
900 Use specified info for remote login. If you specify an URL with user
902 name, the entered password will be cached so that future URL references
903 can use it.
904 version
906 Print lftp version.
908 wait [jobno]
910 wait all
911 Wait for specified job to terminate. If jobno is omitted, wait for last
913 backgrounded job.
914 `wait all' waits for all jobs to terminate.
916 zcat files
918 Same as cat, but filter each file through zcat. (See also cat, more and
920 zmore)
921 zmore files
923 Same as more, but filter each file through zcat. (See also cat, zcat
925 and more)
926 Settings
929 On startup, lftp executes ~/.lftprc and ~/.lftp/rc (or ~/.con‐
930 fig/lftp/rc if ~/.lftp does not exist). You can place aliases and
931 `set' commands there. Some people prefer to see full protocol debug,
932 use `debug' to turn the debug on.
933 There is also a system-wide startup file in /etc/lftp.conf. It can be
935 in different directory, see FILES section.

978 (either backgrounded or foreground).
979 cmd:at-finish (string)
981 the commands in string are executed once when all jobs are done.
982 cmd:at-queue-finish (string)
984 the commands in string are executed once when all jobs in a
985 queue are done.
986 cmd:cls-completion-default (string)

993 default cls command options. They can be overridden by explic‐
994 itly given options.
995 cmd:cls-exact-time (boolean)
997 when true, cls would try to get exact file modification time
998 even if it means more requests to the server.
999 cmd:csh-history (boolean)
1001 enables csh-like history expansion.
1002 cmd:default-protocol (string)
1004 The value is used when `open' is used with just host name with‐
1005 out protocol. Default is `ftp'.
1006 cmd:fail-exit (boolean)
1008 if true, exit when a command fails and the following command is
1009 unconditional (i.e. does not begin with || or &&). lftp exits
1010 after the unconditional command is issued without executing it.
1011 cmd:interactive (tri-boolean)
1013 when true, lftp acts interactively, handles terminal signals and
1014 outputs some extra messages. Default is auto and depends on
1015 stdin being a terminal.
1016 cmd:long-running (seconds)
1018 time of command execution, which is considered as `long' and a
1019 beep is done before next prompt. 0 means off.
1020 cmd:ls-default (string)
1022 default ls argument
1023 cmd:move-background (boolean)
1025 when false, lftp refuses to go to background when exiting. To
1026 force it, use `exit bg'.
1027 cmd:move-background-detach (boolean)
1029 when true (default), lftp detaches itself from the control ter‐
1030 minal when moving to background, it is possible to attach back
1031 using `attach' command; when false, lftp tricks the shell to
1032 move lftp to background process group and continues to run, then
1033 fg shell command brings lftp back to foreground unless it has
1034 done all jobs and terminated.
1035 cmd:prompt (string)
1037 The prompt. lftp recognizes the following backslash-escaped spe‐
1038 cial characters that are decoded as follows:
1039 \@ insert @ if the current remote site user is not default
1040 \a an ASCII bell character (07)
1041 \e an ASCII escape character (033)
1042 \h the remote hostname you are connected to
1043 \n newline
1044 \s the name of the client (lftp)
1045 \S current slot name
1046 \u the username of the remote site user you are logged in as
1047 \U the URL of the remote site (e.g.,
1048 ftp://g437.ub.gu.se/home/james/src/lftp)
1049 \v the version of lftp (e.g., 2.0.3)
1050 \w the current working directory at the remote site
1051 \W the base name of the current working directory at the
1052 remote site
1053 \l the current working directory at the local site
1054 \L the base name of the current working directory at the
1055 local site
1056 \nnn the character corresponding to the octal number nnn
1057 \\ a backslash
1058 \? skips next character if previous substitution was empty.
1059 \[ begin a sequence of non-printing characters, which could
1060 be used to embed a terminal control sequence into the
1061 prompt
1062 \] end a sequence of non-printing characters
1063 cmd:parallel (number)
1066 Number of jobs run in parallel in non-interactive mode. For
1067 example, this may be useful for scripts with multiple `get' com‐
1068 mands. Note that setting this to a value greater than 1 changes
1069 conditional execution behaviour, basically makes it inconsis‐
1070 tent.
1071 cmd:queue-parallel (number)
1073 Number of jobs run in parallel in a queue.
1074 cmd:remote-completion (boolean)
1076 a boolean to control whether or not lftp uses remote completion.
1077 When true, Tab key guesses if the word being completed should be
1078 a remote file name. Meta-Tab does remote completion always. So
1079 you can force remote completion with Meta-Tab when cmd:remote-
1080 completion is false or when the guess is wrong.
1081 cmd:save-cwd-history (boolean)
1083 when true, lftp saves last CWD of each site to
1084 ~/.local/share/lftp/cwd_history or ~/.lftp/cwd_history, allowing
1085 to do ``cd -'' after lftp restart. Default is true.
1086 cmd:save-rl-history (boolean)
1088 when true, lftp saves readline history to
1089 ~/.local/share/lftp/rl_history or ~/.lftp/rl_history on exit.
1090 Default is true.

1093 when false, lftp does not show status line on terminal. Default
1094 is true.
1095 cmd:set-term-status (boolean)
1097 when true, lftp updates terminal status if supported (e.g.
1098 xterm). The closure for this setting is the terminal type from
1099 TERM environment variable.
1100 cmd:status-interval (timeinterval)
1102 the time interval between status updates.
1103 cmd:stifle-rl-history (number)
1105 the number of lines to keep in readline history.
1106 cmd:term-status (string)
1108 the format string to use to display terminal status. The closure
1109 for this setting is the terminal type from TERM environment
1110 variable. Default uses ``tsl'' and ``fsl'' termcap values.
1111 The following escapes are supported:
1113 \a bell
1115 \e escape
1116 \n new line
1117 \s "lftp"
1118 \v lftp version
1119 \T the status string
1120 cmd:time-style (string)
1122 This setting is the default value for cls --time-style option.
1123 cmd:trace (boolean)
1125 when true, lftp prints the commands it executes (like sh -x).
1126 cmd:verify-host (boolean)
1128 if true, lftp resolves host name immediately in `open' command.
1129 It is also possible to skip the check for a single `open' com‐
1130 mand if `&' is given, or if ^Z is pressed during the check.
1131 cmd:verify-path (boolean)
1133 if true, lftp checks the path given in `cd' command. It is also
1134 possible to skip the check for a single `cd' command if `&' is
1135 given, or if ^Z is pressed during the check. Examples:
1136 set cmd:verify-path/hftp://* false
1137 cd directory &
1138 cmd:verify-path-cached (boolean)
1140 When false, `cd' to a directory known from cache as existent
1141 will succeed immediately. Otherwise the verification will
1142 depend on cmd:verify-path setting.
1143 color:use-color (tri-boolean)
1145 when true, cls command and completion output colored file list‐
1146 ings according to color:dir-colors setting. When set to auto,
1147 colors are used when output is a terminal.
1148 color:dir-colors (string)
1150 file listing color description. By default the value of LS_COL‐
1151 ORS environment variable is used. See dircolors(1).
1152 dns:SRV-query (boolean)
1154 query for SRV records and use them before gethostbyname. The SRV
1155 records are only used if port is not explicitly specified. See
1156 RFC2052 for details.
1157 dns:cache-enable (boolean)
1159 enable DNS cache. If it is off, lftp resolves host name each
1160 time it reconnects.
1161 dns:cache-expire (time interval)
1163 time to live for DNS cache entries. It has format <num‐
1164 ber><unit>+, e.g. 1d12h30m5s or just 36h. To disable expira‐
1165 tion, set it to `inf' or `never'.
1166 dns:cache-size (number)
1168 maximum number of DNS cache entries.
1169 dns:fatal-timeout (time interval)
1171 limit the time for DNS queries. If DNS server is unavailable too
1172 long, lftp will fail to resolve a given host name. Set to
1173 `never' to disable.
1174 dns:order (list of protocol names)
1176 sets the order of DNS queries. Default is ``inet6 inet'' which
1177 means first look up address in inet6 family, then inet and use
1178 them in that order. To disable inet6 (AAAA) lookup, set this
1179 variable to ``inet''.
1180 dns:use-fork (boolean)
1182 if true, lftp will fork before resolving host address. Default
1183 is true.
1184 dns:max-retries (number)
1186 If zero, there is no limit on the number of times lftp will try
1187 to lookup an address. If > 0, lftp will try only this number of
1188 times to look up an address of each address family in dns:order.
1189 dns:name (string)
1191 This setting can be used to substitute a host name alias with
1192 another name or IP address. The host name alias is used as the
1193 setting closure, the substituted name or IP address is in the
1194 value. Multiple names or IP addresses can be separated by comma.
1195 file:charset (string)
1197 local character set. It is set from current locale initially.
1198 file:use-lock (boolean)
1200 when true, lftp uses advisory locking on local files when open‐
1201 ing them.
1202 file:use-fallocate (boolean)
1204 when true, lftp uses fallocate(2) or posix_fallocate(3) to pre-
1205 allocate storage space and reduce file fragmentation in pget and
1206 torrent commands.
1207 fish:auto-confirm (boolean)
1209 when true, lftp answers ``yes'' to all ssh questions, in partic‐
1210 ular to the question about a new host key. Otherwise it answers
1211 ``no''.
1212 fish:charset (string)
1214 the character set used by fish server in requests, replies and
1215 file listings. Default is empty which means the same as local.
1216 fish:connect-program (string)
1218 the program to use for connecting to remote server. It should
1219 support `-l' option for user name, `-p' for port number. Default
1220 is `ssh -a -x'. You can set it to `rsh', for example. For pri‐
1221 vate key authentication add `-i' option with the key file.
1222 fish:shell (string)
1224 use specified shell on server side. Default is /bin/sh. On some
1225 systems, /bin/sh exits when doing cd to a non-existent direc‐
1226 tory. lftp can handle that but it has to reconnect. Set it to
1227 /bin/bash for such systems if bash is installed.
1228 ftp:acct (string)
1230 Send this string in ACCT command after login. The result is
1231 ignored. The closure for this setting has format user@host.
1232 ftp:anon-pass (string)

1247 size from the "150 Opening data connection" reply.
1248 ftp:charset (string)
1250 the character set used by FTP server in requests, replies and
1251 file listings. Default is empty which means the same as local.
1252 This setting is only used when the server does not support UTF8.
1253 ftp:client (string)
1255 the name of FTP client to send with CLNT command, if supported
1256 by server. If it is empty, then no CLNT command will be sent.
1257 ftp:compressed-re (regex)

1264 sive mode). Default is true, exception is the loopback inter‐
1265 face.
1266 ftp:fix-pasv-address (boolean)
1268 if true, lftp will try to correct address returned by server for
1269 PASV command in case when server address is in public network
1270 and PASV returns an address from a private network. In this case
1271 lftp would substitute server address instead of the one returned
1272 by PASV command, port number would not be changed. Default is
1273 true.
1274 ftp:fxp-passive-source (boolean)
1276 if true, lftp will try to set up source FTP server in passive
1277 mode first, otherwise destination one. If first attempt fails,
1278 lftp tries to set them up the other way. If the other disposi‐
1279 tion fails too, lftp falls back to plain copy. See also ftp:use-
1280 fxp.
1281 ftp:home (string)
1283 Initial directory. Default is empty string which means auto. Set
1284 this to `/' if you don't like the look of %2F in FTP URLs. The
1285 closure for this setting has format user@host.
1286 ftp:ignore-pasv-address (boolean)
1288 If true, lftp uses control connection address instead of the one
1289 returned in PASV reply for data connection. This can be useful
1290 for broken NATs. Default is false.
1291 ftp:list-empty-ok (boolean)
1293 if set to false, empty lists from LIST command will be treated
1294 as incorrect, and another method (NLST) will be used.
1295 ftp:list-options (string)

1298 be useful to set this to `-a' if server does not show dot (hid‐
1299 den) files by default. Default is empty.
1300 ftp:mode-z-level (number)
1302 compression level (0-9) for uploading with MODE Z.
1303 ftp:nop-interval (seconds)
1305 delay between NOOP commands when downloading tail of a file.
1306 This is useful for FTP servers which send "Transfer complete"
1307 message before flushing data transfer. In such cases NOOP com‐
1308 mands can prevent connection timeout.
1309 ftp:passive-mode (boolean)
1311 sets passive FTP mode. This can be useful if you are behind a
1312 firewall or a dumb masquerading router. In passive mode lftp
1313 uses PASV command, not the PORT command which is used in active
1314 mode. In passive mode lftp itself makes the data connection to
1315 the server; in active mode the server connects to lftp for data
1316 transfer. Passive mode is the default.
1317 ftp:port-ipv4 (ipv4 address)
1319 specifies an IPv4 address to send with PORT command. Default is
1320 empty which means to send the address of local end of control
1321 connection.
1322 ftp:port-range (from-to)
1324 allowed port range for the local side of the data connection.
1325 Format is min-max, or `full' or `any' to indicate any port.
1326 Default is `full'.
1327 ftp:prefer-epsv (boolean)
1329 use EPSV as preferred passive mode. Default is `false'.
1330 ftp:proxy (URL)
1332 specifies FTP proxy to use. To disable proxy set this to empty
1333 string. Note that it is a FTP proxy which uses FTP protocol, not
1334 FTP over HTTP. Default value is taken from environment variable
1335 ftp_proxy if it starts with ``ftp://''. If your FTP proxy
1336 requires authentication, specify user name and password in the
1337 URL. If ftp:proxy starts with http:// then hftp protocol (FTP
1338 over HTTP proxy) is used instead of FTP automatically.
1339 ftp:proxy-auth-type (string)
1341 When set to ``joined'', lftp sends ``user@proxy_user@ftp.exam‐
1342 ple.org'' as user name to proxy, and ``password@proxy_password''
1343 as password.
1344 When set to ``joined-acct'', lftp sends ``user@ftp.example.org
1346 proxy_user'' (with space) as user name to proxy. The site pass‐
1347 word is sent as usual and the proxy password is expected in the
1348 following ACCT command.
1349 When set to ``open'', lftp first sends proxy user and proxy
1351 password and then ``OPEN ftp.example.org'' followed by ``USER
1352 user''. The site password is then sent as usual.
1353 When set to ``user'' (default), lftp first sends proxy user and
1355 proxy password and then ``user@ftp.example.org'' as user name.
1356 The site password is then sent as usual.
1357 When set to ``proxy-user@host'', lftp first sends ``USER
1359 proxy_user@ftp.example.org'', then proxy password. The site user
1360 and password are then sent as usual.
1361 ftp:rest-list (boolean)
1363 allow usage of REST command before LIST command. This might be
1364 useful for large directories, but some FTP servers silently
1365 ignore REST before LIST.
1366 ftp:rest-stor (boolean)
1368 if false, lftp will not try to use REST before STOR. This can be
1369 useful for some buggy servers which corrupt (fill with zeros)
1370 the file if REST followed by STOR is used.
1371 ftp:retry-530 (regex)
1373 Retry on server reply 530 for PASS command if text matches this
1374 regular expression. This setting should be useful to distin‐
1375 guish between overloaded server (temporary condition) and incor‐
1376 rect password (permanent condition).
1377 ftp:retry-530-anonymous (regex)
1379 Additional regular expression for anonymous login, like
1380 ftp:retry-530.
1381 ftp:site-group (string)
1383 Send this string in SITE GROUP command after login. The result
1384 is ignored. The closure for this setting has format user@host.
1385 ftp:skey-allow (boolean)
1387 allow sending skey/opie reply if server appears to support it.
1388 On by default.
1389 ftp:skey-force (boolean)
1391 do not send plain text password over the network, use skey/opie
1392 instead. If skey/opie is not available, assume failed login. Off
1393 by default.
1394 ftp:ssl-allow (boolean)
1396 if true, try to negotiate SSL connection with FTP server for
1397 non-anonymous access. Default is true. This and other SSL set‐
1398 tings are only available if lftp was compiled with an ssl/tls
1399 library.
1400 ftp:ssl-auth (string)
1402 the argument for AUTH command, can be one of SSL, TLS, TLS-P,
1403 TLS-C. See RFC4217 for explanations. By default TLS or SSL will
1404 be used, depending on FEAT reply.
1405 ftp:ssl-data-use-keys (boolean)
1407 if true, lftp loads ssl:key-file for protected data connection
1408 too. When false, it does not, and the server can match data and
1409 control connections by session ID. Default is true.
1410 ftp:ssl-force (boolean)
1412 if true, refuse to send password in clear when server does not
1413 support SSL. Default is false.
1414 ftp:ssl-protect-data (boolean)
1416 if true, request SSL connection for data transfers. This pro‐
1417 vides privacy and transmission error correction. Was cpu-inten‐
1418 sive on old CPUs. Default is true.
1419 ftp:ssl-protect-fxp (boolean)
1421 if true, request SSL connection for data transfer between two
1422 FTP servers in FXP mode. CPSV or SSCN command will be used in
1423 that case. If SSL connection fails for some reason, lftp would
1424 try unprotected FXP transfer unless ftp:ssl-force is set for any
1425 of the two servers. Default is true.
1426 ftp:ssl-protect-list (boolean)
1428 if true, request SSL connection for file list transfers. Default
1429 is true.
1430 ftp:ssl-use-ccc (boolean)
1432 if true, lftp would issue CCC command after logon, thus disable
1433 ssl protection layer on control connection.
1434 ftp:stat-interval (time interval)
1436 interval between STAT commands. Default is 1 second.
1437 ftp:strict-multiline (boolean)
1439 when true, lftp strictly checks for multiline reply format
1440 (expects it to end with the same code as it started with). When
1441 false, this check is relaxed.
1442 ftp:sync-mode (boolean)
1444 if true, lftp will send one command at a time and wait for
1445 response. This might be useful if you are using a buggy FTP
1446 server or router. When it is off, lftp sends a pack of commands
1447 and waits for responses - it speeds up operation when round trip
1448 time is significant. Unfortunately it does not work with all
1449 FTP servers and some routers have troubles with it, so it is on
1450 by default.
1451 ftp:timezone (string)
1453 Assume this timezone for time in listings returned by LIST com‐
1454 mand. This setting can be GMT offset [+|-]HH[:MM[:SS]] or any
1455 valid TZ value (e.g. Europe/Moscow or
1456 MSK-3MSD,M3.5.0,M10.5.0/3). The default is GMT. Set it to an
1457 empty value to assume local timezone specified by environment
1458 variable TZ.
1459 ftp:too-many-re (regexp)
1461 Decrease the dynamic connection limit when 421 reply line
1462 matches this regular expression.
1463 ftp:trust-feat (string)
1465 When true, assume that FEAT returned data are correct and don't
1466 use common protocol extensions like SIZE, MDTM, REST if they are
1467 not listed. Default is false.
1468 ftp:use-abor (boolean)
1470 if false, lftp does not send ABOR command but closes data con‐
1471 nection immediately.
1472 ftp:use-allo (boolean)
1474 when true, lftp sends ALLO command before uploading a file.
1475 ftp:use-feat (boolean)
1477 when true (default), lftp uses FEAT command to determine
1478 extended features of ftp server.
1479 ftp:use-fxp (boolean)
1481 if true, lftp will try to set up direct connection between two
1482 ftp servers.
1483 ftp:use-hftp (boolean)
1485 when ftp:proxy points to an http proxy, this setting selects
1486 hftp method (GET, HEAD) when true, and CONNECT method when
1487 false. Default is true.
1488 ftp:use-ip-tos (boolean)
1490 when true, lftp uses IPTOS_LOWDELAY for control connection and
1491 IPTOS_THROUGHPUT for data connections.
1492 ftp:lang (boolean)
1494 the language selected with LANG command, if supported as indi‐
1495 cated by FEAT response. Default is empty which means server
1496 default.
1497 ftp:use-mdtm (boolean)
1499 when true (default), lftp uses MDTM command to determine file
1500 modification time.
1501 ftp:use-mdtm-overloaded (boolean)
1503 when true, lftp uses two argument MDTM command to set file modi‐
1504 fication time on uploaded files. Default is false.
1505 ftp:use-mlsd (boolean)
1507 when true, lftp will use MLSD command for directory listing if
1508 supported by the server.
1509 ftp:use-mode-z (boolean)
1511 when true, lftp will use "MODE Z" if supported by the server to
1512 perform compressed transfers.
1513 ftp:use-site-idle (boolean)
1515 when true, lftp sends `SITE IDLE' command with net:idle argu‐
1516 ment. Default is false.
1517 ftp:use-site-utime (boolean)
1519 when true, lftp sends 5-argument `SITE UTIME' command to set
1520 file modification time on uploaded files. Default is true.
1521 ftp:use-site-utime2 (boolean)
1523 when true, lftp sends 2-argument `SITE UTIME' command to set
1524 file modification time on uploaded files. Default is true. If
1525 5-argument `SITE UTIME' is also enabled, 2-argument command is
1526 tried first.
1527 ftp:use-size (boolean)
1529 when true (default), lftp uses SIZE command to determine file
1530 size.
1531 ftp:use-stat (boolean)
1533 if true, lftp sends STAT command in FXP mode transfer to know
1534 how much data has been transferred. See also ftp:stat-interval.
1535 Default is true.
1536 ftp:use-stat-for-list (boolean)
1538 when true, lftp uses STAT instead of LIST command. By default
1539 `.' is used as STAT argument. Using STAT, lftp avoids creating
1540 data connection for directory listing. Some servers require spe‐
1541 cial options for STAT, use ftp:list-options to specify them
1542 (e.g. -la).
1543 ftp:use-telnet-iac (boolean)
1545 when true (default), lftp uses TELNET IAC command and follows
1546 TELNET protocol as specified in RFC959. When false, it does not
1547 follow TELNET protocol and thus does not double 255 (0xFF, 0377)
1548 character and does not prefix ABOR and STAT commands with TELNET
1549 IP+SYNCH signal.
1550 ftp:use-tvfs (tri-boolean)
1552 When set to auto, usage of TVFS feature depends on FEAT server
1553 reply. Otherwise this setting tells whether use it or not. In
1554 short, if a server supports TVFS feature then it uses unix-like
1555 paths.
1556 ftp:use-utf8 (boolean)
1558 if true, lftp sends `OPTS UTF8 ON' to the server to activate
1559 UTF-8 encoding (if supported). Disable it if the file names have
1560 a different encoding and the server has a trouble with it.
1561 ftp:use-quit (boolean)
1563 if true, lftp sends QUIT before disconnecting from ftp server.
1564 Default is true.
1565 ftp:verify-address (boolean)
1567 verify that data connection comes from the network address of
1568 control connection peer. This can possibly prevent data connec‐
1569 tion spoofing which can lead to data corruption. Unfortunately,
1570 this can fail for certain ftp servers with several network
1571 interfaces, when they do not set outgoing address on data
1572 socket, so it is disabled by default.
1573 ftp:verify-port (boolean)
1575 verify that data connection has port 20 (ftp-data) on its remote
1576 end. This can possibly prevent data connection spoofing by
1577 users of remote host. Unfortunately, too many windows and even
1578 unix ftp servers forget to set proper port on data connection,
1579 thus this check is off by default.
1580 ftp:web-mode (boolean)
1582 disconnect after closing data connection. This can be useful for
1583 totally broken ftp servers. Default is false.
1584 ftps:initial-prot (string)
1586 specifies initial PROT setting for FTPS connections. Should be
1587 one of: C, S, E, P, or empty. Default is empty which means
1588 unknown, so that lftp will use PROT command unconditionally. If
1589 PROT command turns out to be unsupported, then Clear mode would
1590 be assumed.
1591 hftp:cache (boolean)
1593 allow server/proxy side caching for ftp-over-http protocol.
1594 hftp:cache-control (string)
1596 specify corresponding HTTP request header.
1597 hftp:decode (boolean)
1599 when true, lftp automatically decodes the entity in hftp proto‐
1600 col when Content-Encoding header value matches deflate, gzip,
1601 compress, x-gzip or x-compress.
1602 hftp:proxy (URL)
1604 specifies HTTP proxy for FTP-over-HTTP protocol (hftp). The pro‐
1605 tocol hftp cannot work without a HTTP proxy, obviously. Default
1606 value is taken from environment variable ftp_proxy if it starts
1607 with ``http://'', otherwise from environment variable
1608 http_proxy. If your FTP proxy requires authentication, specify
1609 user name and password in the URL.
1610 hftp:use-allprop (boolean)
1612 if true, lftp will send `<allprop/>' request body in `PROPFIND'
1613 requests, otherwise it will send an empty request body.
1614 hftp:use-authorization (boolean)
1616 if set to off, lftp will send password as part of URL to the
1617 proxy. This may be required for some proxies (e.g. M-soft).
1618 Default is on, and lftp will send password as part of Authoriza‐
1619 tion header.
1620 hftp:use-head (boolean)
1622 if set to off, lftp will try to use `GET' instead of `HEAD' for
1623 hftp protocol. While this is slower, it may allow lftp to work
1624 with some proxies which don't understand or mishandle ``HEAD
1625 ftp://'' requests.
1626 hftp:use-mkcol (boolean)
1628 if set to off, lftp will try to use `PUT' instead of `MKCOL' to
1629 create directories with hftp protocol. Default is off.
1630 hftp:use-propfind (boolean)
1632 if set to off, lftp will not try to use `PROPFIND' to get direc‐
1633 tory contents with hftp protocol and use `GET' instead. Default
1634 is off. When enabled, lftp will also use PROPPATCH to set file
1635 modification time after uploading.
1636 hftp:use-range (boolean)
1638 when true, lftp will use Range header for transfer restart.
1639 hftp:use-type (boolean)
1641 If set to off, lftp won't try to append `;type=' to URLs passed
1642 to proxy. Some broken proxies don't handle it correctly.
1643 Default is on.
1644 http:accept, http:accept-charset, http:accept-encoding, http:accept-
1646 language (string)
1647 specify corresponding HTTP request headers.
1648 http:authorization (string)
1650 the authorization to use by default, when no user is specified.
1651 The format is ``user:password''. Default is empty which means no
1652 authorization.
1653 http:cache (boolean)
1655 allow server/proxy side caching.
1656 http:cache-control (string)
1658 specify corresponding HTTP request header.
1659 http:cookie (string)
1661 send this cookie to server. A closure is useful here:
1662 set cookie/www.somehost.com "param=value"
1663 http:decode (boolean)
1665 when true, lftp automatically decodes the entity when Content-
1666 Encoding header value matches deflate, gzip, compress, x-gzip or
1667 x-compress.
1668 http:post-content-type (string)
1670 specifies value of Content-Type HTTP request header for POST
1671 method. Default is ``application/x-www-form-urlencoded''.
1672 http:proxy (URL)
1674 specifies HTTP proxy. It is used when lftp works over HTTP pro‐
1675 tocol. Default value is taken from environment variable
1676 http_proxy. If your proxy requires authentication, specify user
1677 name and password in the URL.
1678 http:put-method (PUT or POST)
1680 specifies which HTTP method to use on put.
1681 http:put-content-type (string)
1683 specifies value of Content-Type HTTP request header for PUT
1684 method.
1685 http:referer (string)
1687 specifies value for Referer HTTP request header. Single dot `.'
1688 expands to current directory URL. Default is `.'. Set to empty
1689 string to disable Referer header.
1690 http:set-cookies (boolean)
1692 if true, lftp modifies http:cookie variables when Set-Cookie
1693 header is received.
1694 http:use-allprop (boolean)
1696 if true, lftp will send `<allprop/>' request body in `PROPFIND'
1697 requests, otherwise it will send an empty request body.
1698 http:use-mkcol (boolean)
1700 if set to off, lftp will try to use `PUT' instead of `MKCOL' to
1701 create directories with HTTP protocol. Default is on.
1702 http:use-propfind (boolean)
1704 if set to off, lftp will not try to use `PROPFIND' to get direc‐
1705 tory contents with HTTP protocol and use `GET' instead. Default
1706 is off. When enabled, lftp will also use PROPPATCH to set `Last-
1707 Modified' property after a file upload.
1708 http:use-range (boolean)
1710 when true, lftp will use Range header for transfer restart.
1711 http:user-agent (string)
1713 the string lftp sends in User-Agent header of HTTP request.
1714 https:proxy (string)
1716 specifies https proxy. Default value is taken from environment
1717 variable https_proxy.
1718 log:enabled (boolean)
1720 when true, the log messages are output. The closure for this and
1721 other `log:' variables is either `debug' for debug messages or
1722 `xfer' for transfer logging.
1723 log:file (string)
1725 the target output file for logging. When empty, stderr is used.
1726 log:level (number)
1728 the log verbosity level. Currently it's only defined for `debug'
1729 closure.
1730 log:max-size (number)
1732 maximum size of the log file. When the size is reached, the file
1733 is renamed and started anew.
1734 log:prefix-error (string)
1736 log:prefix-note (string)
1738 log:prefix-recv (string)
1740 log:prefix-send (string)
1742 the prefixes for corresponding types of debug messages.
1743 log:show-ctx (boolean)
1745 log:show-pid (boolean)
1747 log:show-time (boolean)
1749 select additional information in the log messages.
1750 mirror:dereference (boolean)
1752 when true, mirror will dereference symbolic links by default.
1753 You can override it by --no-dereference option. Default if
1754 false.
1755 mirror:exclude-regex (regex)
1757 specifies default exclusion pattern. You can override it by
1758 --include option.
1759 mirror:include-regex (regex)
1761 specifies default inclusion pattern. It is used just after mir‐
1762 ror:exclude-regex is applied. It is never used if mir‐
1763 ror:exclude-regex is empty.
1764 mirror:no-empty-dirs (boolean)
1766 when true, mirror doesn't create empty directories (like
1767 --no-empty-dirs option).
1768 mirror:sort-by (string)
1770 specifies order of file transfers. Valid values are: name, name-
1771 desc, size, size-desc, date, date-desc. When the value is name
1772 or name-desc, then mirror:order setting also affects the order
1773 or transfers.
1774 mirror:order (list of patterns)
1776 specifies order of file transfers when sorting by name. E.g.
1777 setting this to "*.sfv *.sum" makes mirror to transfer files
1778 matching *.sfv first, then ones matching *.sum and then all
1779 other files. To process directories after other files, add "*/"
1780 to the end of pattern list.
1781 mirror:overwrite (boolean)
1783 when true, mirror will overwrite plain files instead of removing
1784 and re-creating them.
1785 mirror:parallel-directories (boolean)
1787 if true, mirror will start processing of several directories in
1788 parallel when it is in parallel mode. Otherwise, it will trans‐
1789 fer files from a single directory before moving to other direc‐
1790 tories.
1791 mirror:parallel-transfer-count (number)
1793 specifies number of parallel transfers mirror is allowed to
1794 start. You can override it with --parallel option. A closure
1795 can be matched against source or target host names, the minimum
1796 number greater than 0 is used.
1797 mirror:require-source (boolean)
1799 When true, mirror requires a source directory to be specified
1800 explicitly, otherwise it is supposed to be the current direc‐
1801 tory.
1802 mirror:set-permissions (boolean)
1804 When set to off, mirror won't try to copy file and directory
1805 permissions. You can override it by --perms option. Default is
1806 on.
1807 mirror:skip-noaccess (boolean)
1809 when true, mirror does not try to download files which are obvi‐
1810 ously inaccessible by the permission mask. Default is false.
1811 mirror:use-pget-n (number)
1813 specifies -n option for pget command used to transfer every sin‐
1814 gle file under mirror. A closure can be matched against source
1815 or target host names, the minimum number greater than 0 is used.
1816 When the value is less than 2, pget is not used.
1817 module:path (string)
1819 colon separated list of directories to look for modules. Can be
1820 initialized by environment variable LFTP_MODULE_PATH. Default is
1821 `PKGLIBDIR/VERSION:PKGLIBDIR'.
1822 net:connection-limit (number)
1824 maximum number of concurrent connections to the same site. 0
1825 means unlimited.
1826 net:connection-limit-timer (time interval)
1828 increase the dynamic connection limit after this time interval.
1829 net:connection-takeover (boolean)
1831 if true, foreground connections have priority over background
1832 ones and can interrupt background transfers to complete a fore‐
1833 ground operation.
1834 net:idle (time interval)
1836 disconnect from server after this idle time. Default is 3 min‐
1837 utes.
1838 net:limit-rate (bytes per second)
1840 limit transfer rate on data connection. 0 means unlimited. You
1841 can specify two numbers separated by colon to limit download and
1842 upload rate separately. Suffixes are supported, e.g. 100K means
1843 102400.
1844 net:limit-max (bytes)
1846 limit accumulating of unused limit-rate. 0 means twice of limit-
1847 rate.
1848 net:limit-total-rate (bytes per second)
1850 limit transfer rate of all connections in sum. 0 means unlim‐
1851 ited. You can specify two numbers separated by colon to limit
1852 download and upload rate separately. Note that sockets have
1853 receive buffers on them, this can lead to network link load
1854 higher than this rate limit just after transfer beginning. You
1855 can try to set net:socket-buffer to relatively small value to
1856 avoid this.
1857 If you specify a closure, then rate limitation will be applied to sum
1859 of connections to a single matching host.
1860 net:limit-total-max (bytes)
1862 limit accumulating of unused limit-total-rate. 0 means twice of
1863 limit-total-rate.
1864 net:max-retries (number)
1866 the maximum number of sequential tries of an operation without
1867 success. 0 means unlimited. 1 means no retries.
1868 net:no-proxy (string)
1870 contains comma separated list of domains for which proxy should
1871 not be used. Default is taken from environment variable
1872 no_proxy.
1873 net:persist-retries (number)
1875 ignore this number of hard errors. Useful to login to buggy FTP
1876 servers which reply 5xx when there is too many users.
1877 net:reconnect-interval-base (seconds)
1879 sets the base minimal time between reconnects. Actual interval
1880 depends on net:reconnect-interval-multiplier and number of
1881 attempts to perform an operation.
1882 net:reconnect-interval-max (seconds)
1884 sets maximum reconnect interval. When current interval after
1885 multiplication by net:reconnect-interval-multiplier reaches this
1886 value (or exceeds it), it is reset back to net:reconnect-inter‐
1887 val-base.
1888 net:reconnect-interval-multiplier (real number)
1890 sets multiplier by which base interval is multiplied each time
1891 new attempt to perform an operation fails. When the interval
1892 reaches maximum, it is reset to base value. See net:reconnect-
1893 interval-base and net:reconnect-interval-max.
1894 net:socket-bind-ipv4 (ipv4 address)
1896 bind all IPv4 sockets to specified address. This can be useful
1897 to select a specific network interface to use. Default is empty
1898 which means not to bind IPv4 sockets, operating system will
1899 choose an address automatically using routing table.
1900 net:socket-bind-ipv6 (ipv6 address)
1902 the same for IPv6 sockets.
1903 net:socket-buffer (bytes)
1905 use given size for SO_SNDBUF and SO_RCVBUF socket options. 0
1906 means system default.
1907 net:socket-maxseg (bytes)

1913 sets the network protocol timeout.
1914 pget:default-n (number)
1916 default number of chunks to split the file to in pget.
1917 pget:min-chunk-size (number)
1919 minimal chunk size to split the file to.
1920 pget:save-status (time interval)

1923 saving of the status file. The status is saved to a file with
1924 suffix .lftp-pget-status.
1925 sftp:auto-confirm (boolean)
1927 when true, lftp answers ``yes'' to all ssh questions, in partic‐
1928 ular to the question about a new host key. Otherwise it answers
1929 ``no''.
1930 sftp:charset (string)
1932 the character set used by SFTP server in file names and file
1933 listings. Default is empty which means the same as local. This
1934 setting is only used for SFTP protocol version prior to 4. Ver‐
1935 sion 4 and later always use UTF-8.
1936 sftp:connect-program (string)
1938 the program to use for connecting to remote server. It should
1939 support `-l' option for user name, `-p' for port number. Default
1940 is `ssh -a -x'. For private key authentication add `-i' option
1941 with the key file.
1942 sftp:max-packets-in-flight (number)
1944 The maximum number of unreplied packets in flight. If round trip
1945 time is significant, you should increase this and size-
1946 read/size-write. Default is 16.
1947 sftp:protocol-version (number)
1949 The protocol number to negotiate. Default is 6. The actual pro‐
1950 tocol version used depends on the server.
1951 sftp:server-program (string)
1953 The server program implementing SFTP protocol. If it does not
1954 contain a slash `/', it is considered a ssh2 subsystem and -s
1955 option is used when starting connect-program. Default is
1956 `sftp'. You can use rsh as transport level protocol like this:
1957 set sftp:connect-program rsh
1958 set sftp:server-program /usr/libexec/openssh/sftp-server
1959 Similarly you can run SFTP over SSH1.
1960 sftp:size-read (number)
1962 Block size for reading. Default is 0x8000.
1963 sftp:size-write (number)
1965 Block size for writing. Default is 0x8000.

1971 use specified directory as Certificate Authority certificate
1972 repository (OpenSSL only).
1973 ssl:check-hostname (boolean)
1975 when true, lftp checks if the host name used to connect to the
1976 server corresponds to the host name in its certificate.
1977 ssl:crl-file (path to file)
1979 use specified file as Certificate Revocation List certificate.
1980 ssl:crl-path (path to directory)
1982 use specified directory as Certificate Revocation List certifi‐
1983 cate repository (OpenSSL only).
1984 ssl:key-file (path to file)
1986 use specified file as your private key. This setting is only
1987 used for ftps and https protocols. For sftp and fish protocols
1988 use sftp:connect-program and fish:connect-program respectively
1989 (add `-i' option to ssh).
1990 ssl:cert-file (path to file)
1992 use specified file as your certificate.
1993 ssl:use-sni (boolean)
1995 when true, use Server Name Indication (SNI) TLS extension.
1996 ssl:verify-certificate (boolean)
1998 if set to yes, then verify server's certificate to be signed by
1999 a known Certificate Authority and not be on Certificate Revoca‐
2000 tion List. You can specify either host name or certificate fin‐
2001 gerprint in the closure.
2002 ssl:priority (string)
2004 free form priority string for GnuTLS. If built with OpenSSL the
2005 understood values are + or - followed by SSL3.0, TLS1.0, TLS1.1
2006 or TLS1.2, separated by :. Example:
2007 set ssl:priority "NORMAL:-SSL3.0:-TLS1.0:-TLS1.1:+TLS1.2"

2010 IP address to send to the tracker. Specify it if you are using
2011 an HTTP proxy.
2012 torrent:ipv6 (ipv6 address)
2014 IPv6 address to send to the tracker. By default, first found
2015 global unicast address is used.
2016 torrent:max-peers (number)
2018 maximum number of peers for a torrent. Least used peers are
2019 removed to maintain this limit.
2020 torrent:port-range (from-to)
2022 port range to accept connections on. A single port is selected
2023 when a torrent starts.
2024 torrent:retracker (URL)
2026 explicit retracker URL, e.g. `http://retracker.local/announce'.
2027 torrent:save-metadata (boolean)
2029 when true, lftp saves metadata of each torrent it works with to
2030 ~/.local/share/lftp/torrent/md or ~/.lftp/torrent/md directory
2031 and loads it from there if necessary.
2032 torrent:seed-max-time (time interval)
2034 maximum seed time. After this period of time a complete torrent
2035 shuts down independently of ratio. It can be set to infinity if
2036 needed.
2037 torrent:seed-min-peers (number)
2039 minimum number of peers when the torrent is complete. If there
2040 are less, new peers are actively searched for.
2041 torrent:stop-min-ppr (real number)
2043 minimum per-piece-ratio to stop seeding. Use it to avoid a situ‐
2044 ation when a popular piece causes quick raise of the total
2045 ratio.
2046 torrent:stop-on-ratio (real number)
2048 torrent stops when it's complete and ratio reached this number.
2049 torrent:timeout (time interval)
2051 maximum time without any progress. When it's reached, the tor‐
2052 rent shuts down.
2053 torrent:use-dht (boolean)
2055 when true, DHT is used.
2056 xfer:auto-rename(boolean)
2058 suggested filenames provided by the server are used if user
2059 explicitly sets this option to `on'. As this could be security
2060 risk, default is off.
2061 xfer:backup-suffix (string)
2063 a time format string (see strftime(3)) for backup file name when
2064 replacing an existing file.
2065 xfer:clobber (boolean)
2067 if this setting is off, get commands will not overwrite existing
2068 files and generate an error instead.
2069 xfer:destination-directory (path or URL to directory)
2071 This setting is used as default -O option for get and mget com‐
2072 mands. Default is empty, which means current directory (no -O
2073 option).
2074 xfer:disk-full-fatal (boolean)
2076 when true, lftp aborts a transfer if it cannot write target file
2077 because of full disk or quota; when false, lftp waits for disk
2078 space to be freed.
2079 xfer:eta-period (seconds)
2081 the period over which weighted average rate is calculated to
2082 produce ETA.
2083 xfer:eta-terse (boolean)
2085 show terse ETA (only high order parts). Default is true.
2086 xfer:keep-backup (boolean)
2088 when true, the backup file created before replacing an existing
2089 file is not removed after successful transfer.
2090 xfer:make-backup (boolean)
2092 when true, lftp renames pre-existing file adding xfer:backup-
2093 suffix instead of overwriting it.
2094 xfer:max-redirections (number)
2096 maximum number of redirections. This can be useful for download‐
2097 ing over HTTP. 0 prohibits redirections.
2098 xfer:parallel (number)
2100 the default number of parallel transfers in a single
2101 get/put/mget/mput command.
2102 xfer:rate-period (seconds)
2104 the period over which weighted average rate is calculated to be
2105 shown.
2106 xfer:temp-file-name (string)
2108 temporary file name pattern, first asterisk is replaced by the
2109 original file name.
2110 xfer:timeout (time interval)
2112 maximum time without any transfer progress. It can be used to
2113 limit maximum time to retry a transfer from a server not sup‐
2114 porting transfer restart.
2115 xfer:use-temp-file (boolean)
2117 when true, a file will be transferred to a temporary file in the
2118 same directory and then renamed.
2119 xfer:verify (boolean)
2121 when true, verify-command is launched after successful transfer
2122 to validate file integrity. Zero exit code of that command
2123 should indicate correctness of the file.
2124 xfer:verify-command (string)
2126 the command to validate file integrity. The only argument is the
2127 path to the file.
2128 The name of a variable can be abbreviated unless it becomes ambiguous.
2131 The prefix before `:' can be omitted too. You can set one variable sev‐
2132 eral times for different closures, and thus you can get a particular
2133 settings for particular state. The closure is to be specified after
2134 variable name separated with slash `/'.
2135 The closure for `dns:', `net:', `ftp:', `http:', `hftp:' domain vari‐
2137 ables is currently just the host name as you specify it in the `open'
2138 command (with some exceptions where closure is meaningless, e.g.
2139 dns:cache-size). For some `cmd:' domain variables the closure is cur‐
2140 rent URL without path. For `log:' domain variables the closure is
2141 either `debug' or `xfer'. For other variables it is not currently
2142 used. See examples in the sample lftp.conf.
2143 Certain commands and settings take a time interval parameter. It has
2145 the format Nx[Nx...], where N is time amount (floating point) and x is
2146 time unit: d - days, h - hours, m - minutes, s - seconds. Default unit
2147 is second. E.g. 5h30m or 5.5h. Also the interval can be `infinity',
2148 `inf', `never', `forever' - it means infinite interval. E.g. `sleep
2149 forever' or `set dns:cache-expire never'.
2150 Boolean settings can be one of (true, on, yes, 1, +) for a True value
2152 or one of (false, off, no, 0, -) for a False value.
2153 Tri-boolean settings have either a boolean value or `auto'.
2155 Integer settings can have a suffix: k - kibi, m - mebi, g - gigi, etc.
2157 They can also have a prefix: 0 - octal, 0x - hexadecimal.
2158 FTP asynchronous mode (pipelining)
2161 Lftp can speed up FTP operations by sending several commands at once
2162 and then checking all the responses. See ftp:sync-mode variable. Some‐
2163 times this does not work, thus synchronous mode is the default. You can
2164 try to turn synchronous mode off and see if it works for you. It is
2165 known that some network software dealing with address translation works
2166 incorrectly in the case of several FTP commands in one network packet.
2167 RFC959 says: ``The user-process sending another command before the com‐
2169 pletion reply would be in violation of protocol; but server-FTP pro‐
2170 cesses should queue any commands that arrive while a preceding command
2171 is in progress''. Also, RFC1123 says: ``Implementors MUST NOT assume
2172 any correspondence between READ boundaries on the control connection
2173 and the Telnet EOL sequences (CR LF).'' and ``a single READ from the
2174 control connection may include more than one FTP command''.
2175 So it must be safe to send several commands at once, which speeds up
2177 operation a lot and seems to work with all Unix and VMS based ftp
2178 servers. Unfortunately, windows based servers often cannot handle sev‐
2179 eral commands in one packet, and so cannot some broken routers.
2180
2183 -d Switch on debugging mode.
2184 -e commands
2186 Execute given commands and don't exit.
2187 -p port
2189 Use the given port to connect.
2190 -u user[,pass]
2192 Use the given username and password to connect. Remember to
2193 quote the password properly in the shell. Also note that it is
2194 not secure to specify the password on command line, use ~/.netrc
2195 file or LFTP_PASSWORD environment variable together with
2196 --env-password option. Alternatively you can use ssh-based pro‐
2197 tocols with authorized keys, so you don't have to enter a pass‐
2198 word.
2199 --norc Don't execute rc files from the home directory.
2201 --rcfile file
2203 Execute commands from the file. May be specified multiple times.
2204 -f script_file
2206 Execute commands in the file and exit. This option must be used
2207 alone without other arguments (except --norc).
2208 -c commands
2210 Execute the given commands and exit. Commands can be separated
2211 with a semicolon, `&&' or `||'. Remember to quote the commands
2212 argument properly in the shell. This option must be used alone
2213 without other arguments (except --norc).
2214 Other open options may also be given on the lftp command line.
2216
2219 The following environment variables are processed by lftp:
2220 EDITOR Used as local editor for the edit command.
2222 HOME Used for (local) tilde (`~') expansion.
2224 SHELL Used by the ! command to determine the shell to run.
2226 PAGER This should be the name of the pager to use. It's used by the
2228 more and zmore commands.
2229 http_proxy, https_proxy
2231 Used to set initial http:proxy, hftp:proxy and https:proxy vari‐
2232 ables.
2233 ftp_proxy
2235 Used to set initial ftp:proxy or hftp:proxy variables, depending
2236 on URL protocol used in this environment variable.
2237 no_proxy
2239 Used to set initial net:no-proxy variable.
2240 LFTP_MODULE_PATH
2242 Used to set initial module:path variable.
2243 LFTP_HOME
2245 Used to locate the directory that stores user-specific configu‐
2246 ration files. If unset, ~/.lftp will be used. Please note that
2247 if this directory does not exist, then XDG directories will be
2248 used.
2249 LFTP_PASSWORD
2251 Used for --env-password open option.
2252 LS_COLORS
2254 used to set initial color:dir-colors variable.
2255 XDG_CONFIG_HOME, XDG_DATA_HOME, XDG_CACHE_HOME
2257 Used to locate the directories for user-specific files when
2258 ~/.lftp (or $LFTP_HOME directory) does not exist. Defaults are
2259 ~/.config, ~/.local/share and ~/.cache respectively. The suffix
2260 /lftp is appended to make the full path to the directories.
2261
2264 /etc/lftp.conf
2265 system-wide startup file. Actual location depends on
2266 --sysconfdir configure option. It is /etc when prefix is /usr,
2267 /usr/local/etc by default.
2268 ~/.config/lftp/rc or ~/.lftp/rc, ~/.lftprc
2271 These files are executed on lftp startup after /etc/lftp.conf.
2272 ~/.local/share/lftp/log or ~/.lftp/log
2274 The file things are logged to when lftp moves into the back‐
2275 ground in nohup mode.
2276 ~/.local/share/lftp/transfer_log or ~/.lftp/transfer_log
2278 The file transfers are logged to when log:enabled/xfer setting
2279 is set to `yes'. The location can be changed by log:file/xfer
2280 setting.
2281 ~/.local/share/lftp/bookmarks or ~/.lftp/bookmarks
2283 The file is used to store lftp's bookmarks. See the bookmark
2284 command.
2285 ~/.local/share/lftp/cwd_history or ~/.lftp/cwd_history
2287 The file is used to store last working directories for each site
2288 visited.
2289 ~/.local/share/lftp/bg/ or ~/.lftp/bg/
2291 The directory is used to store named sockets for backgrounded
2292 lftp processes.
2293 ~/.cache/lftp/DHT/ or ~/.lftp/DHT/"
2295 The directory is used to store DHT id and nodes cache for IPv4
2296 and IPv6. File name suffix is the host name.
2297 ~/.cache/lftp/edit/ or ~/.lftp/edit/"
2299 The directory is used to store temporary files for edit command.
2300 ~/.local/share/lftp/torrent/md/ or ~/.lftp/torrent/md/"
2302 The directory is used to store torrent metadata. It is espe‐
2303 cially useful for magnet links, cached metadata can be loaded
2304 from the directory. It can also serve as torrent history, file
2305 names are the info_hash of torrents.
2306 ~/.netrc
2308 The file is consulted to get default login and password to a
2309 server when it is specified without a protocol to the `open'
2310 command. Passwords are also searched here if an URL with user
2311 name but with no password is used.
