md5sum [OPTION]... [FILE]...
Print or check MD5 (128-bit) checksums. With no FILE, or when FILE is
-, read standard input.
read in binary mode
read MD5 sums from the FILEs and check them
read in text mode (default)
The following three options are useful only when verifying checksums:
don't print OK for each successfully verified file
don't output anything, status code shows success
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 character indicating type (`*' for
binary, ` ' for text), and name for each FILE.
