MD5SUM(1)MD5SUM(1)NAMEmd5sum - compute and check MD5 message digest
SYNOPSISmd5sum [-bhtvV] [-c file] [-s[string]] [--binary] [--check=file]
[--help] [--string[=string]] [--text] [--verbose] [--version] [file...]
DESCRIPTION
This documentation is no longer being maintained and may be inaccurate
or incomplete. The Texinfo documentation is now the authoritative
source.
This manual page documents the GNU version of md5sum. md5sum produces
for each input file a 128-bit "fingerprint" or "message-digest" or it
can check with the output of a former run whether the message digests
are still the same (i.e. whether the files changed).
OPTIONS
-b, --binary
Treat all input files as binary. This normally does not make
any difference on UN*X systems but some systems have a different
internal and external representation of texts (especially the
end-of-line characters).
-c, --check=file
file should be the output of a former run of md5sum. The file
has in each line the MD5 sum, a binary/text flag, and a file
name. This file will be opened (with each possible relative
path) and the message digest is computed. If it is not the same
as given in this line it will be marked as failed.
-h --help
Print a usage message and exit.
-s, --string=string
Instead of computing the message digest for a file compute it
for the given string. The result is the same as for a file with
contains exactly this string.
-t, --text
Treat all input files as text files. This is the reverse option
to --binary.
-v, --verbose
Verbosely write information about the process.
-V, --version
Print version information on standard output then exit.
