read in binary mode

-c

--tag

create a BSD-style checksum

--ignore-missing

--quiet

don't print OK for each successfully verified file

--status

don't output anything, status code shows success

--strict

-w

--help

--version

output version information and exitThe sums are computed as described in FIPS-180-2. When checking, the input should be a former output of thisprogram. The default mode is to print a line with checksum, a space, a character indicating input mode ('*'for binary, ' ' for text or where binary is insignificant), and name for each FILE.AUTHORWritten by Ulrich Drepper, Scott Miller, and David Madore.REPORTING BUGSGNU coreutils online help: <http://www.gnu.org/software/coreutils/>Report sha384sum translation bugs to <http://translationproject.org/team/>COPYRIGHTCopyright © 2017 Free Software Foundation, Inc.
