shasum - Print or Check SHA Checksums

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/Mac
  -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.
