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.
−b
, −−binary
read in binary mode
−c
, −−check
read MD5 sums from the FILEs and check them
−−tag
create a BSD−style checksum
−t
, −−text
read in text mode (default)
−z
, −−zero
end each output line with NUL, not newline, and disable file name escaping
−−ignore−missing
don't fail or report status for missing files
−−quiet
don't print OK for each successfully verified file
−−status
don't output anything, status code shows success
−−strict
exit non−zero for improperly formatted checksum lines
−w
, −−warn
warn about improperly formatted 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 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)
