## Name

md5sum - compute and check MD5 message digest

## Synopsis

md5sum [OPTION] [FILE]...
md5sum [OPTION] --check [FILE]

## Description

Print or check MD5 checksums. With no FILE, or when FILE is -, read standard input.

-b, --binary
  read files in binary mode (default on DOS/Windows)
-c, --check
  check MD5 sums against given list
-t, --text
  read files in text mode (default)

### The following two options are useful only when verifying checksums:

--status
  don't output anything, status code shows success
-w, --warn
  warn about improperly formated MD5 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 character indicating type (`*' for binary, ` ' for text), and name for each FILE.
