SHA224SUM(1)			  User Commands 		    SHA224SUM(1)

NAME
     sha224sum - compute and check SHA224 message digest

SYNOPSIS
     sha224sum [OPTION]... [FILE]...

DESCRIPTION
     Print or check SHA224 (224-bit) checksums.

     With no FILE, or when FILE is -, read standard input.

     -b, --binary
	    read in binary mode

     -c, --check
	    read checksums 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 3874.  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.

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