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

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

   The following three 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

       -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 for-
       mer  output of this program.  The default mode is to print a line with checksum, a charac-
       ter indicating type (`*' for binary, ` ' for text), and name for each FILE.
