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)

    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.

BUGS

The MD5 algorithm should not be used any more for security related purposes. Instead, better use an SHA-2 algorithm, implemented in the programs sha224sum(1), sha256sum(1), sha384sum(1), sha512sum(1)
