sha384sum

compute and check SHA384 message digest

TLDR

Calculate the SHA384 checksum for a file

$ sha384sum [path/to/file]

Calculate SHA384 checksums for multiple files

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

Calculate and save the list of SHA384 checksums to a file

$ sha384sum [path/to/file1] [path/to/file2] > [path/to/file.sha384]

Read a file of SHA384 sums and verify all files have matching checksums

$ sha384sum --check [path/to/file.sha384]

Only show a message for missing files or when verification fails

$ sha384sum --check --quiet [path/to/file.sha384]

Only show a message for files for which verification fails, ignoring missing files

$ sha384sum --ignore-missing --check --quiet [path/to/file.sha384]

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.
