NAME

6       cksfv - tests and creates simple file verification (SFV) listings
7

SYNOPSIS

9       cksfv [-bciqrL] [-C dir] [-f file] [-g path] [file ...]
10

DESCRIPTION

12       Some files that you download will come with a .sfv file.  cksfv is used
13       to verify that the files that you received are the same as  the  origi‐
14       nals.  cksfv uses the .sfv file to verify the downloaded files.  It can
15       also be used to create new .sfv files.
16
17       md5sum (1) or sha1sum (1) are the suggested  ways  of  checksuming  new
18       files. cksfv should only be used for compatibility with other systems.

OPTIONS

22       These options are available
23
24       -b     strip  dirnames  from  filenames  that are checksumed. loads the
25              files from original positions, but prints only basenames to cat‐
26              alogue in sfv file.
27
28       -c     Use  stdout for printing progress and final resolution (files OK
29              or some errors detected). This is useful for  external  programs
30              analysing output of cksfv. This also forces fflushes on the out‐
31              put when needed.
32
33       -C dir  change to directory for processing
34
35       -f file
36               .sfv file to verify
37
38       -g path
39               Go to the path name directory and verify the sfv file
40
41       -i     ignore case on filenames
42
43       -q     quiet, only prints error messages
44
45       -v     verbose, by default this option is on
46
47       -r     recurse directories and check  the  .sfv  files  in  each.  This
48              option cannot be used in conjunction with the -f option.
49
50       -L     follow  symlinks when recursing subdirectories. This option only
51              has meaning when used in conjunction with the -r option.

EXAMPLES

55       Check checksums of files listed in 'foo/files.sfv':
56       cksfv -g foo/files.sfv
57
58       Create checksums for a bunch of files:
59       cksfv *.gz > files.sfv
60
61       Check checksum of case-insensitive filenames listed in 'files.sfv'.
62       This is sometimes useful with files created by operating systems
63       that have case-insensitive filesystem names.
64       cksfv -i -g files.sfv
65
66       Check checksums of files 'foo' and 'bar' listed in 'files.sfv':
67       cksfv -g files.sfv foo bar
68
69       Create checksums of files matching /foo/bar/* and strip dirnames away:
70       cksfv -b /foo/bar/* > files.sfv
71
72       Recursively scan /foo/bar and verify each .sfv file:
73       cksfv -C /foo/bar -r
74
75       Same as previous, but starting from the current working directory
76       and also following symlinks during recursion:
77       cksfv -r -L
