NAME

       shasum - Print or Check SHA Checksums

SYNOPSIS

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

         -a, --algorithm    1 (default), 224, 256, 384, 512
         -b, --binary       read files in binary mode (default on DOS/Windows)
         -c, --check        check SHA sums against given list
         -p, --portable     read files in portable mode
                                produces same digest on Windows/Unix/MacOS 9
         -t, --text         read files in text mode (default)

        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 SHA checksum lines

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

        The sums are computed as described in FIPS PUB 180-2.  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 portable, ` ' for text), and name for each FILE.
