shasum - Print or Check SHA Checksums
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 -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 formatted SHA checksum lines --help display this help and exit --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 text), and name for each FILE.
