About sha512sum

The sha512sum command computes and checks a SHA512 message digest.

Description

Print or check SHA512 (512-bit) checksums. With no FILE, or when FILE is -, read standard input.

sha512sum syntax

sha512sum [OPTION]... [FILE]...

Options

-b, --binary Read in binary mode.
-c, --check Read SHA512 sums from the FILEs and check them.
--tag Create a BSD-style checksum.
-t, --text Read in text mode (default).

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

The following four options are useful only when verifying checksums:

--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 character indicating input mode ('*' for binary, space for text), and name for each FILE.

sha512sum examples

sha512sum example.iso

Running the above command would give the SHA512 checksum of the example.iso file in the current directory. Below is an example of how the output may appear with the full SHA512 checksum followed by the file name.
