6 ftp - file transfer program
7
9 ftp [-adfginpstvx] [-m GSS Mech] [-T timeout]
10 [hostname [port]]
11
14 The ftp command is the user interface to the Internet standard File
15 Transfer Protocol (FTP). ftp transfers files to and from a remote net‐
16 work site.
17 The host and optional port with which ftp is to communicate can be
20 specified on the command line. If this is done, ftp immediately
21 attempts to establish a connection to an FTP server on that host. Oth‐
22 erwise, ftp enters its command interpreter and awaits instructions from
23 the user. When ftp is awaiting commands from the user, it displays the
24 prompt ftp>.
25
27 The following options can be specified at the command line, or to the
28 command interpreter:
29 -a Uses GSSAPI authentication only. If the authentication
31 fails, this option closes the connection.
32 -d Enables debugging.
35 -f Forwards local security credentials to the remote server.
38 -g Disables filename "globbing".
41 -i Turns off interactive prompting during multiple file
44 transfers.
45 -m Specifies the GSS-API mechanism to use. The default is to
48 use the kerberos_v5 mechanism. Supported alternatives are
49 defined in /etc/gss/mech (see mech(4)).
50 -n Does not attempt "auto-login" upon initial connection. If
53 auto-login is not disabled, ftp checks the .netrc file in
54 the user's home directory for an entry describing an
55 account on the remote machine. If no entry exists, ftp
56 prompts for the login name of the account on the remote
57 machine (the default is the login name on the local
58 machine), and, if necessary, prompts for a password and
59 an account with which to login.
60 -p Enables passive mode for data transfers. This command is
63 useful when connecting to a remote host from behind a
64 connection filtering firewall.
65 -s Skips the SYST command that is sent by default to all
68 remote servers upon connection. The system command is
69 what enables the automatic use of binary mode rather than
70 the protocol default ascii mode.
71 As some older servers cannot handle the ftp command, this
73 directive is provided to allow inter-operability with
74 these servers.
75 -t Enables packet tracing (unimplemented).
78 -T timeout Enables global connection timer, specified in seconds
81 (decimal). There is a timer for the control connection
82 that is reset when anything is sent to the server and
83 disabled while the client is prompting for user input.
84 Another independent timer is used to monitor incoming or
85 outgoing data connections.
86 -v Shows all responses from the remote server, as well as
89 report on data transfer statistics. This is turned on by
90 default if ftp is running interactively with its input
91 coming from the user's terminal.
92 -x Attempts to use GSSAPI for authentication and encryption.
95 Data and Command channel protection is set to "private".
96 The following commands can be specified to the command interpreter:
100 !
102 [ command ] Runs command as a shell command on the local machine.
104 If no command is given, invokes an interactive shell.
105 $ macro-name [ args ]
108 Executes the macro macro-name that was defined with the macdef com‐
110 mand. Arguments are passed to the macro unglobbed.
111 account [ passwd ]
114 Supplies a supplemental password required by a remote system for
116 access to resources once a login has been successfully completed.
117 If no argument is included, the user is prompted for an account
118 password in a non-echoing input mode.
119 append local-file [ remote-file ]
122 Appends a local file to a file on the remote machine. If remote-
124 file is not specified, the local file name is used, subject to
125 alteration by any ntrans or nmap settings. File transfer uses the
126 current settings for "representation type", "file structure", and
127 "transfer mode".
128 ascii
131 Sets the "representation type" to "network ASCII". This is the
133 default type.
134 bell
137 Sounds a bell after each file transfer command is completed.
139 binary
142 Sets the "representation type" to "image".
144 bye
147 Terminates the FTP session with the remote server and exit ftp. An
149 EOF also terminates the session and exit.
150 case
153 Toggles remote computer file name case mapping during mget com‐
155 mands. When case is on (default is off), remote computer file names
156 with all letters in upper case are written in the local directory
157 with the letters mapped to lower case.
158 cd remote-directory
161 Changes the working directory on the remote machine to remote-
163 directory.
164 cdup
167 Changes the remote machine working directory to the parent of the
169 current remote machine working directory.
170 clear
173 Sets the protection level on data transfers to "clear". If no ADAT
175 command succeeded, then this is the default protection level.
176 close
179 Terminates the FTP session with the remote server, and return to
181 the command interpreter. Any defined macros are erased.
182 cr
185 Toggles RETURN stripping during "network ASCII" type file
187 retrieval. Records are denoted by a RETURN/LINEFEED sequence during
188 "network ASCII" type file transfer. When cr is on (the default),
189 RETURN characters are stripped from this sequence to conform with
190 the UNIX system single LINEFEED record delimiter. Records on non-
191 UNIX-system remote hosts can contain single LINEFEED characters;
192 when an "network ASCII" type transfer is made, these LINEFEED char‐
193 acters can be distinguished from a record delimiter only when cr is
194 off.
195 delete remote-file
198 Deletes the file remote-file on the remote machine.
200 debug
203 Toggles debugging mode. When debugging is on, ftp prints each com‐
205 mand sent to the remote machine, preceded by the string ->.
206 dir [ remote-directory [ local-file ]]
209 Prints a listing of the directory contents in the directory,
211 remote-directory, and, optionally, placing the output in local-
212 file. If no directory is specified, the current working directory
213 on the remote machine is used. If no local file is specified, or
214 local-file is −, output is sent to the terminal.
215 disconnect
218 A synonym for close.
220 form [ format-name ]
223 Sets the carriage control format subtype of the "representation
225 type" to format-name. The only valid format-name is non-print,
226 which corresponds to the default "non-print" subtype.
227 get remote-file [ local-file ]
230 Retrieves the remote-file and store it on the local machine. If the
232 local file name is not specified, it is given the same name it has
233 on the remote machine, subject to alteration by the current case,
234 ntrans, and nmap settings. The current settings for "representation
235 type", "file structure", and "transfer mode" are used while trans‐
236 ferring the file.
237 glob
240 Toggles filename expansion, or "globbing", for mdelete, mget and
242 mput. If globbing is turned off, filenames are taken literally.
243 Globbing for mput is done as in sh(1). For mdelete and mget, each
245 remote file name is expanded separately on the remote machine, and
246 the lists are not merged.
247 Expansion of a directory name is likely to be radically different
249 from expansion of the name of an ordinary file: the exact result
250 depends on the remote operating system and FTP server, and can be
251 previewed with the command, mls remote-files −.
252 mget and mput are not meant to transfer entire directory subtrees
254 of files. You can do this by transferring a tar(1) archive of the
255 subtree (using a "representation type" of "image" as set by the
256 binary command).
257 hash
260 Toggles hash-sign (#) printing for each data block transferred. The
262 size of a data block is 8192 bytes.
263 help [ command ]
266 Prints an informative message about the meaning of command. If no
268 argument is given, ftp prints a list of the known commands.
269 lcd [ directory ]
272 Changes the working directory on the local machine. If no directory
274 is specified, the user's home directory is used.
275 ls [ -al | remote-directory [ local-file ]]
278 By default, prints an abbreviated listing of the contents of a
280 directory on the remote machine. This default behavior can be
281 changed to make ls a synonym of the dir command. This change can be
282 achieved by setting FTP_LS_SENDS_NLST to 'no' in /etc/default/ftp
283 or in the environment. See ftp(4) for details.
284 The -a option lists all entries, including those that begin with a
286 dot (.), which are normally not listed. The -l option lists files
287 in long format, giving mode, number of links, owner, group, size in
288 bytes, and time of last modification for each file. If the file is
289 a special file, the size field instead contains the major and minor
290 device numbers rather than a size. If the file is a symbolic link,
291 the filename is printed followed by "→" and the pathname of the
292 referenced file.
293 If remote-directory is left unspecified, the current working direc‐
295 tory is used.
296 If no local file is specified, or if local-file is −, the output is
298 sent to the terminal.
299 macdef macro-name
302 Defines a macro. Subsequent lines are stored as the macro macro-
304 name. A null line (consecutive NEWLINE characters in a file or
305 RETURN characters from the terminal) terminates macro input mode.
306 There is a limit of 16 macros and 4096 total characters in all
307 defined macros. Macros remain defined until a close command is exe‐
308 cuted.
309 The macro processor interprets $ and \ as special characters. A $
311 followed by a number (or numbers) is replaced by the corresponding
312 argument on the macro invocation command line. A $ followed by an i
313 signals that macro processor that the executing macro is to be
314 looped. On the first pass, $i is replaced by the first argument on
315 the macro invocation command line; on the second pass, it is
316 replaced by the second argument, and so on. A \ followed by any
317 character is replaced by that character. Use the \ to prevent spe‐
318 cial treatment of the $.
319 mdelete remote-files
322 Deletes the remote-files on the remote machine.
324 mdir remote-files local-file
327 Like dir, except multiple remote files can be specified. If inter‐
329 active prompting is on, ftp prompts the user to verify that the
330 last argument is indeed the target local file for receiving mdir
331 output.
332 mget remote-files
335 Expands the remote-files on the remote machine and do a get for
337 each file name thus produced. See glob for details on the filename
338 expansion. Resulting file names are processed according to case,
339 ntrans, and nmap settings. Files are transferred into the local
340 working directory, which can be changed with lcd directory. New
341 local directories can be created with ! mkdir directory.
342 mkdir directory-name
345 Makes a directory on the remote machine.
347 mls remote-files local-file
350 Like ls(1), except multiple remote files can be specified. If
352 interactive prompting is on, ftp prompts the user to verify that
353 the last argument is indeed the target local file for receiving mls
354 output.
355 mode [ mode-name ]
358 Sets the "transfer mode" to mode-name. The only valid mode-name is
360 stream, which corresponds to the default "stream" mode. This imple‐
361 mentation only supports stream, and requires that it be specified.
362 mput local-files
365 Expands wild cards in the list of local files given as arguments
367 and do a put for each file in the resulting list. See glob for
368 details of filename expansion. Resulting file names are processed
369 according to ntrans and nmap settings.
370 nlist [ -al | remote-directory [ local-file ]]
373 Prints an abbreviated listing of the contents of a directory on the
375 remote machine, listing only those files that can be retrieved by
376 the get command, unless the -a or -l option is used. If remote-
377 directory is left unspecified, the current working directory is
378 used.
379 The -a option lists all entries, including those that begin with a
381 dot (.), which are normally not listed. The -l option lists files
382 in long format the same way it does when used with the ls command.
383 nmap [ inpattern outpattern ]
386 Sets or unsets the filename mapping mechanism. If no arguments are
388 specified, the filename mapping mechanism is unset. If arguments
389 are specified, remote filenames are mapped during mput commands and
390 put commands issued without a specified remote target filename. If
391 arguments are specified, local filenames are mapped during mget
392 commands and get commands issued without a specified local target
393 filename.
394 This command is useful when connecting to a non-UNIX-system remote
396 host with different file naming conventions or practices. The map‐
397 ping follows the pattern set by inpattern and outpattern. inpattern
398 is a template for incoming filenames (which can have already been
399 processed according to the ntrans and case settings). Variable tem‐
400 plating is accomplished by including the sequences $1, $2, ..., $9
401 in inpattern. Use \ to prevent this special treatment of the $
402 character. All other characters are treated literally, and are used
403 to determine the nmap inpattern variable values.
404 For example, given inpattern $1.$2 and the remote file name
406 mydata.data, $1 would have the value mydata, and $2 would have the
407 value data.
408 The outpattern determines the resulting mapped filename. The
410 sequences $1, $2, ..., $9 are replaced by any value resulting from
411 the inpattern template. The sequence $0 is replaced by the original
412 filename. Additionally, the sequence [seq1,seq2] is replaced by
413 seq1 if seq1 is not a null string; otherwise it is replaced by
414 seq2.
415 For example, the command nmap $1.$2.$3 [$1,$2].[$2,file] would
417 yield the output filename myfile.data for input filenames
418 myfile.data and myfile.data.old, myfile.file for the input filename
419 myfile, and myfile.myfile for the input filename .myfile. SPACE
420 characters can be included in outpattern, as in the example nmap $1
421 | sed "s/ *$//" > $1. Use the \ character to prevent special treat‐
422 ment of the $, [, ], and ,, characters.
423 ntrans [ inchars [ outchars ] ]
426 Sets or unsets the filename character translation mechanism. If no
428 arguments are specified, the filename character translation mecha‐
429 nism is unset. If arguments are specified, characters in remote
430 filenames are translated during mput commands and put commands
431 issued without a specified remote target filename, and characters
432 in local filenames are translated during mget commands and get com‐
433 mands issued without a specified local target filename.
434 This command is useful when connecting to a non-UNIX-system remote
436 host with different file naming conventions or practices. Charac‐
437 ters in a filename matching a character in inchars are replaced
438 with the corresponding character in outchars. If the character's
439 position in inchars is longer than the length of outchars, the
440 character is deleted from the file name.
441 Only 16 characters can be translated when using the ntrans command
443 under ftp. Use case (described above) if needing to convert the
444 entire alphabet.
445 open host [ port ]
448 Establishes a connection to the specified host FTP server. An
450 optional port number can be supplied, in which case, ftp attempts
451 to contact an FTP server at that port. If the auto-login option is
452 on (default setting), ftp also attempts to automatically log the
453 user in to the FTP server.
454 passive
457 Toggles passive mode. When passive mode is turned on, the ftp
459 client sends the PASV command requesting that the FTP server open a
460 port for the data connection and return the address of that port.
461 The remote server listens on that port and the client connects to
462 it. When passive mode is turned off, the ftp client sends the PORT
463 command to the server specifying an address for the remote server
464 to connect back to. Passive mode is useful when the connections to
465 the ftp client are controlled, for example, when behind a firewall.
466 When connecting to an IPv6-enabled FTP server, EPSV can be used in
467 place of PASV and EPRT in place of PORT.
468 private
471 Sets the protection level on data transfers to "private". Data
473 transmissions are confidentiality— and integrity—protected by
474 encryption. If no ADAT command succeeded, then the only possible
475 level is "clear".
476 prompt
479 Toggles interactive prompting. Interactive prompting occurs during
481 multiple file transfers to allow the user to selectively retrieve
482 or store files. By default, prompting is turned on. If prompting is
483 turned off, any mget or mput transfers all files, and any mdelete
484 deletes all files.
485 protect protection-level
488 Sets the protection level on data transfers to protection-level.
490 The valid protection levels are "clear" for unprotected data trans‐
491 missions, "safe" for data transmissions that are integrity-pro‐
492 tected by cryptographic checksum, and "private" for data transmis‐
493 sions that are confidentiality— and integrity— protected by encryp‐
494 tion. If no ADAT command succeeded, then the only possible level is
495 "clear". If no level is specified, the current level is printed.
496 The default protection level is "clear".
497 proxy ftp-command
500 Executes an FTP command on a secondary control connection. This
502 command allows simultaneous connection to two remote FTP servers
503 for transferring files between the two servers. The first proxy
504 command should be an open, to establish the secondary control con‐
505 nection. Enter the command proxy ? to see other FTP commands exe‐
506 cutable on the secondary connection.
507 The following commands behave differently when prefaced by proxy:
509 open does not define new macros during the auto-login process,
510 close does not erase existing macro definitions, get and mget
511 transfer files from the host on the primary control connection to
512 the host on the secondary control connection, and put, mputd, and
513 append transfer files from the host on the secondary control con‐
514 nection to the host on the primary control connection.
515 Third party file transfers depend upon support of the PASV command
517 by the server on the secondary control connection.
518 put local-file [ remote-file ]
521 Stores a local file on the remote machine. If remote-file is left
523 unspecified, the local file name is used after processing according
524 to any ntrans or nmap settings in naming the remote file. File
525 transfer uses the current settings for "representation type", "file
526 structure", and "transfer mode".
527 pwd
530 Prints the name of the current working directory on the remote
532 machine.
533 quit
536 A synonym for bye.
538 quote arg1 arg2 ...
541 Sends the arguments specified, verbatim, to the remote FTP server.
543 A single FTP reply code is expected in return. (The remotehelp com‐
544 mand displays a list of valid arguments.)
545 quote should be used only by experienced users who are familiar
547 with the FTP protocol.
548 recv remote-file [ local-file ]
551 A synonym for get.
553 reget remote-file [ local-file ]
556 The reget command acts like get, except that if local-file exists
558 and is smaller than remote-file, local-file is presumed to be a
559 partially transferred copy of remote-file and the transfer is con‐
560 tinued from the apparent point of failure. This command is useful
561 when transferring large files over networks that are prone to drop‐
562 ping connections.
563 remotehelp [ command-name ]
566 Requests help from the remote FTP server. If a command-name is
568 specified it is supplied to the server as well.
569 rename from to
572 Renames the file from on the remote machine to have the name to.
574 reset
577 Clears reply queue. This command re-synchronizes command/reply
579 sequencing with the remote FTP server. Resynchronization can be
580 necessary following a violation of the FTP protocol by the remote
581 server.
582 restart [ marker ]
585 Restarts the immediately following get or put at the indicated
587 marker. On UNIX systems, marker is usually a byte offset into the
588 file. When followed by an mget, the restart applies to the first
589 get performed. Specifying a marker of 0 clears the restart marker.
590 If no argument is specified, the current restart status is dis‐
591 played.
592 rmdir directory-name
595 Deletes a directory on the remote machine.
597 runique
600 Toggles storing of files on the local system with unique filenames.
602 If a file already exists with a name equal to the target local
603 filename for a get or mget command, a .1 is appended to the name.
604 If the resulting name matches another existing file, a .2 is
605 appended to the original name. If this process continues up to .99,
606 an error message is printed, and the transfer does not take place.
607 The generated unique filename is reported. runique does not affect
608 local files generated from a shell command. The default value is
609 off.
610 safe
613 Sets the protection level on data transfers to "safe". Data trans‐
615 missions are integrity-protected by cryptographic checksum. If no
616 ADAT command succeeded, then the only possible level is "clear".
617 send local-file [ remote-file ]
620 A synonym for put.
622 sendport
625 Toggles the use of PORT commands. By default, ftp attempts to use a
627 PORT command when establishing a connection for each data transfer.
628 The use of PORT commands can prevent delays when performing multi‐
629 ple file transfers. If the PORT command fails, ftp uses the default
630 data port. When the use of PORT commands is disabled, no attempt is
631 made to use PORT commands for each data transfer. This is useful
632 when connected to certain FTP implementations that ignore PORT com‐
633 mands but incorrectly indicate they have been accepted.
634 site arg1 [ arg2 ] ...
637 Sends the arguments specified, verbatim, to the remote FTP server
639 as a SITE command.
640 status
643 Show the current status of ftp.
645 struct [ struct-name ]
648 Sets the file structure to struct-name. The only valid struct-name
650 is file, which corresponds to the default "file" structure. The
651 implementation only supports file, and requires that it be speci‐
652 fied.
653 sunique
656 Toggles storing of files on remote machine under unique file names.
658 The remote FTP server must support the STOU command for successful
659 completion. The remote server reports the unique name. Default
660 value is off.
661 tcpwindow [ size ]
664 Sets the TCP window size to be used for data connections. Specify‐
666 ing a size of 0 stops the explicit setting of the TCP window size
667 on data connections. If no argument is specified, the current set‐
668 ting is displayed.
669 tenex
672 Sets the "representation type" to that needed to talk to TENEX
674 machines.
675 trace
678 Toggles packet tracing (unimplemented).
680 type [ type-name ]
683 Sets the "representation type" to type-name. The valid type-names
685 are ascii for "network ASCII", binary or image for "image", and
686 tenex for "local byte size" with a byte size of 8 (used to talk to
687 TENEX machines). If no type is specified, the current type is
688 printed. The default type is "network ASCII".
689 user user-name [ password [ account ]]
692 Identify yourself to the remote FTP server. If the password is not
694 specified and the server requires it, ftp prompts the user for it
695 (after disabling local echo). If an account field is not specified,
696 and the FTP server requires it, the user is prompted for it. If an
697 account field is specified, an account command is relayed to the
698 remote server after the login sequence is completed if the remote
699 server did not require it for logging in. Unless ftp is invoked
700 with "auto-login" disabled, this process is done automatically on
701 initial connection to the FTP server.
702 verbose
705 Toggles verbose mode. In verbose mode, all responses from the FTP
707 server are displayed to the user. In addition, if verbose mode is
708 on, when a file transfer completes, statistics regarding the effi‐
709 ciency of the transfer are reported. By default, verbose mode is on
710 if ftp's commands are coming from a terminal, and off otherwise.
711 ? [ command ]
714 A synonym for help.
716 Command arguments which have embedded spaces can be quoted with quote
720 (") marks.
721 If any command argument which is not indicated as being optional is not
724 specified, ftp prompts for that argument.
725
727 To abort a file transfer, use the terminal interrupt key. Sending
728 transfers is immediately halted. Receiving transfers are halted by
729 sending an FTP protocol ABOR command to the remote server, and discard‐
730 ing any further data received. The speed at which this is accomplished
731 depends upon the remote server's support for ABOR processing. If the
732 remote server does not support the ABOR command, an ftp> prompt does
733 not appear until the remote server has completed sending the requested
734 file.
735 The terminal interrupt key sequence is ignored when ftp has completed
738 any local processing and is awaiting a reply from the remote server. A
739 long delay in this mode can result from the ABOR processing described
740 above, or from unexpected behavior by the remote server, including vio‐
741 lations of the ftp protocol. If the delay results from unexpected
742 remote server behavior, the local ftp program must be killed by hand.
743
745 Local files specified as arguments to ftp commands are processed
746 according to the following rules.
747 1) If the file name − is specified, the standard input (for reading)
749 or standard output (for writing) is used.
750 2) If the first character of the file name is |, the remainder of
753 the argument is interpreted as a shell command. ftp then forks a
754 shell, using popen(3C) with the argument supplied, and reads
755 (writes) from the standard output (standard input) of that shell.
756 If the shell command includes SPACE characters, the argument must
757 be quoted; for example "| ls -lt". A particularly useful example
758 of this mechanism is: "dir | more".
759 3) Failing the above checks, if globbing is enabled, local file
762 names are expanded according to the rules used in the sh(1); see
763 the glob command. If the ftp command expects a single local file
764 (for example, put), only the first filename generated by the
765 globbing operation is used.
766 4) For mget commands and get commands with unspecified local file
769 names, the local filename is the remote filename, which can be
770 altered by a case, ntrans, or nmap setting. The resulting file‐
771 name can then be altered if runique is on.
772 5) For mput commands and put commands with unspecified remote file
775 names, the remote filename is the local filename, which can be
776 altered by a ntrans or nmap setting. The resulting filename can
777 then be altered by the remote server if sunique is on.

781 The FTP specification specifies many parameters which can affect a file
782 transfer.
783 The "representation type" can be one of "network ASCII", "EBCDIC",
786 "image", or "local byte size" with a specified byte size (for PDP-10's
787 and PDP-20's mostly). The "network ASCII" and "EBCDIC" types have a
788 further subtype which specifies whether vertical format control (NEW‐
789 LINE characters, form feeds, and so on) are to be passed through ("non-
790 print"), provided in TELNET format ("TELNET format controls"), or pro‐
791 vided in ASA (FORTRAN) ("carriage control (ASA)") format. ftp supports
792 the "network ASCII" (subtype "non-print" only) and "image" types, plus
793 "local byte size" with a byte size of 8 for communicating with TENEX
794 machines.
795 The "file structure" can be one of file (no record structure), record,
798 or page. ftp supports only the default value, which is file.
799 The "transfer mode" can be one of stream, block, or compressed. ftp
802 supports only the default value, which is stream.

805 See largefile(5) for the description of the behavior of ftp when
806 encountering files greater than or equal to 2 Gbyte (2^31 bytes).
807 The ftp command is IPv6-enabled. See ip6(7P).

849 Failure to log in can arise from an explicit denial by the remote FTP
850 server because the account is listed in /etc/ftpusers. See in.ftpd(1M)
851 and ftpusers(4).
852 Correct execution of many commands depends upon proper behavior by the
855 remote server.
856 An error in the treatment of carriage returns in the 4.2 BSD code han‐
859 dling transfers with a "representation type" of "network ASCII" has
860 been corrected. This correction can result in incorrect transfers of
861 binary files to and from 4.2 BSD servers using a "representation type"
862 of "network ASCII". Avoid this problem by using the "image" type.
