sha384sum

compute and check SHA384 message digest

TLDR

Calculate the SHA384 checksum for one or more files

$ sha384sum [path/to/file1 path/to/file2 ...]
copy


Calculate and save the list of SHA384 checksums to a file
$ sha384sum [path/to/file1 path/to/file2 ...] > [path/to/file.sha384]
copy


Calculate a SHA384 checksum from stdin
$ [command] | sha384sum
copy


Read a file of SHA384 sums and filenames and verify all files have matching checksums
$ sha384sum --check [path/to/file.sha384]
copy


Only show a message for missing files or when verification fails
$ sha384sum --check --quiet [path/to/file.sha384]
copy


Only show a message when verification fails, ignoring missing files
$ sha384sum --ignore-missing --check --quiet [path/to/file.sha384]
copy

SYNOPSIS

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

DESCRIPTION

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 checksums from the FILEs and check them

--tag

create a BSD-style checksum

-t, --text

read in text mode (default)

-z, --zero

end each output line with NUL, not newline, and disable file name escaping

The following five options are useful only when verifying checksums:

--ignore-missing

don't fail or report status for missing files

--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 space, a character indicating input mode ('*' for binary, ' ' for text or where binary is insignificant), and name for each FILE.

Note: There is no difference between binary mode and text mode on GNU systems.
