sha384sum command

The sha384sum command computes and checks a SHA384 encrypted message digest.


The sha384sum command displays or checks SHA384 (384-bit) checksums. With no FILE, or when FILE is - (a dash), the message digest is read from standard input.


sha384sum [OPTION]... [FILE]...


-b, --binary Read in binary mode.
-c, --check Read SHA384 sums from the FILEs and check them.
--tag Create a BSD-style checksum.
-t, --text Read in text mode (default).

There is no difference between binary and text mode option on GNU system.

The following four 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.
--strict Exit non-zero for improperly formatted checksum lines.
-w, --warn Warn about improperly formatted checksum lines.
--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 input mode ('*' for binary, space for text), and name for each FILE.


sha384sum example.iso

Running the above command would give the SHA384 checksum of the example.iso file in the current directory. Below is an example of how the output may appear with the full SHA384 checksum followed by the file name.
