MD5SUM(1) User Commands MD5SUM(1)
md5sum - compute and check MD5 message digest
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
--tag create a BSD-style checksum
read in text mode (default)
The following five options are useful only when verifying checksums:
don't fail or report status for missing files
don't print OK for each successfully verified file
don't output anything, status code shows success
exit non-zero for improperly formatted checksum lines
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 space, a character indicating input mode ('*' for binary, ' ' for text or where binary is insignificant),
and name for each FILE.
Do not use the MD5 algorithm for security related purposes. Instead, use an SHA-2 algorithm, implemented in the programs sha224sum(1),
sha256sum(1), sha384sum(1), sha512sum(1), or the BLAKE2 algorithm, implemented in b2sum(1)
