md5sum [OPTION]... [FILE]...
MD5SUM(1) User Commands MD5SUM(1) 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 --strict with --check, exit non-zero for any invalid input --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 input mode ('*' for binary, space for text), and name for each FILE. BUGS 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) AUTHOR Written by Ulrich Drepper, Scott Miller, and David Madore.
