MD5SUM(M)                      FSF                      MD5SUM(M)



NAME
       md5sum - compute and check MD5 message digest

SYNOPSIS
       md5sum [OPTION] [FILE]...
       md5sum [OPTION] --check [FILE]

DESCRIPTION
       Print  or check MD5 checksums.  With no FILE, or when FILE
       is -, read standard input.

       -b, --binary
              read files in binary mode (default on DOS/Windows)

       -c, --check
              check MD5 sums against given list

       -t, --text
              read files in text mode (default)

   The following two  options  are  useful  only  when  verifying
       checksums:
       --status
              don't output anything, status code shows success

       -w, --warn
              warn about improperly formated MD5 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 pro-
       gram.   The default mode is to print a line with checksum,
       a character indicating type  (`*'  for  binary,  `  '  for
       text), and name for each FILE.
