sha384sum - compute and check SHA384 message digest
sha384sum [OPTION]... [FILE]...
Print or check SHA384 (384-bit) checksums. With no FILE, or when FILE is -, read standard input. -b, --binary read in binary mode -c, --check read SHA384 sums from the FILEs and check them -t, --text read in text mode (default) The following three options are useful only when verifying checksums: --quiet don't print OK for each successfully verified file --status don't output anything, status code shows success -w, --warn warn about improperly formatted checksum lines --strict with --check, exit non-zero for any invalid input --help display this help and exit --version 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.
