NAME

       shasum - Print or Check SHA Checksums

SYNOPSIS

	Usage: shasum [OPTION]... [FILE]...
	Print or check SHA checksums.
	With no FILE, or when FILE is -, read standard input.

	  -a, --algorithm   1 (default), 224, 256, 384, 512, 512224, 512256
	  -b, --binary	    read in binary mode
	  -c, --check	    read SHA sums from the FILEs and check them
	  -t, --text	    read in text mode (default)
	  -p, --portable    read in portable mode
				produces same digest on Windows/Unix/Mac
	  -0, --01	    read in BITS mode
				ASCII '0' interpreted as 0-bit,
				ASCII '1' interpreted as 1-bit,
				all other characters ignored

	The following two options are useful only when verifying checksums:
	  -s, --status	    don't output anything, status code shows success
	  -w, --warn	    warn about improperly formatted checksum lines

	  -h, --help	    display this help and exit
	  -v, --version     output version information and exit

	When verifying SHA-512/224 or SHA-512/256 checksums, indicate the
	algorithm explicitly using the -a option, e.g.

	  shasum -a 512224 -c checksumfile

	The sums are computed as described in FIPS-180-4.  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, `?' for portable, `^' for BITS), and name for each FILE.

DESCRIPTION

       Running shasum is often the quickest way to compute SHA message digests.  The user simply feeds data to the script through files or
       standard input, and then collects the results from standard output.

       The following command shows how to compute digests for typical inputs such as the NIST test vector "abc":

	       perl -e "print qq(abc)" | shasum

       Or, if you want to use SHA-256 instead of the default SHA-1, simply say:

	       perl -e "print qq(abc)" | shasum -a 256

       Since shasum mimics the behavior of the combined GNU sha1sum, sha224sum, sha256sum, sha384sum, and sha512sum programs, you can install this
       script as a convenient drop-in replacement.

       Unlike the GNU programs, shasum encompasses the full SHA standard by allowing partial-byte inputs.  This is accomplished through the BITS
       option (-0).  The following example computes the SHA-224 digest of the 7-bit message 0001100:

	       perl -e "print qq(0001100)" | shasum -0 -a 224
