sha384sum

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 files for which verification fails

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

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

--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.
