sha512sum (1)

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

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

-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)

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.
