NAME
md5sum - compute and check MD5 message digest
SYNOPSIS

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)
Note: There is no difference between binary and text mode option
on GNU system.
The following two options are useful only when verifying checksums:
--status

-w, --warn

--help display this help and exit
--version

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.
