With no FILE, or when FILE is -, read standard input. -b, --binary read in binary mode -c, --check read SHA224 sums from the FILEs and check them -t, --text read in text mode (default) The following two options are useful only when verifying checksums: --status dont output anything, status code shows success -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.
