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

       --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

The following five options are useful only when verifying checksums:

       --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.

       Note: There is no difference between binary mode and text mode on GNU systems.

BUGS

       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)
