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.
read in binary mode
read SHA256 sums from the FILEs and check them
read in text mode (default)
The following two options are useful only when verifying checksums:
don't output anything, status code shows success
warn about improperly formatted checksum lines
--help display this help and exit
output version information and exit
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.
