With no FILE, or when FILE is -, read standard input. -b, --binary read files in binary mode (default on DOS/Win- dows) -c, --check check SHA1 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 checksum lines --help display this help and exit --version output version information and exit The sums are computed as described in FIPS-180-1.
