sha256sum - compute and check SHA256 message digest
sha256sum [OPTION] [FILE]...
Print or check SHA256 (256-bit) checksums. With no FILE, or when FILE is -, read standard input.
-b, --binary read in binary mode -c, --check read SHA256 sums from the FILEs and check them -t, --text read in text mode (default)
The sums are computed as described in FIPS-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.
--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
