md5sum

MD5SUM(1)								FSF								 MD5SUM(1)

NAME

       md5sum - compute and check MD5 message digest

SYNOPSIS

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

DESCRIPTION

       Print or check MD5 (128-bit) 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 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 type (`*' for binary, ` ' for text), and name for each FILE.
