MD5SUM(1)                        User Commands                       MD5SUM(1)

NAME
       md5sum - compute and check MD5 message digest
SYNOPSIS
       md5sum [OPTION]... [FILE]...
DESCRIPTION
       Print  or check MD5 (128-bit) checksums.  With no FILE, or when FILE is
       -, read standard input.
       -b, --binary
              read in binary mode
       -c, --check
              read MD5 sums from the FILEs and check them
       --tag  create a BSD-style checksum
       -t, --text
              read in text mode (default)
              Note: There is no difference between binary and text mode option
              on GNU system.
   The following four options are useful only when verifying checksums:
       --quiet
              don't print OK for each successfully verified file
       --status
              don't output anything, status code shows success
       --strict
              exit non-zero for improperly formatted checksum lines
       -w, --warn
              warn about improperly formatted checksum lines
       --help display this help and exit
       --version
              output version information and exit
       The  sums  are  computed  as described in RFC 1321.  When checking, the
       input should be a former output of this program.  The default  mode  is
       to  print  a line with checksum, a character indicating input mode ('*'
       for binary, space for text), and name for each FILE.

BUGS
       The MD5 algorithm should not be used any more for security related pur-
       poses.  Instead, better use an SHA-2 algorithm, implemented in the pro-
       grams sha224sum(1), sha256sum(1), sha384sum(1), sha512sum(1)
