sha384sum - Man Page
compute and check SHA384 message digest
Examples (TL;DR)
- Calculate the SHA384 checksum for one or more 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 - Calculate a SHA384 checksum from
stdin:command | sha384sum - Read a file of SHA384 sums and filenames 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 when verification fails, ignoring missing files:
sha384sum --ignore-missing --check --quiet path/to/file.sha384
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.
There is no difference between binary mode and text mode on GNU systems.
