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
-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.
