MD5SUM(1)                        User Commands                       MD5SUM(1)

       md5sum - compute and check MD5 message digest

       md5sum [OPTION]... [FILE]...

       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)

   The following five options are useful only when verifying checksums:
              don't fail or report status for missing files

              don't print OK for each successfully verified file

              don't output anything, status code shows success

              exit non-zero for improperly formatted checksum lines

       -w, --warn
              warn about improperly formatted checksum lines

       --help display this help and exit

              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 space, a character indicating input
       mode ('*' for binary, ' ' for text or where binary  is  insignificant),
       and name for each FILE.

       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)
