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.

TagDescription
-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 two options are useful only when verifying checksums:

TagDescription
--status

-w, --warn warn about improperly formatted checksum lines
--help display this help and exit
--version

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 type (‘*’ for binary, ‘ ’ for text), and name for each FILE.
