NAME
sha512sum - compute and check SHA512 message digest
SYNOPSIS
sha512sum [OPTION]... [FILE]...
DESCRIPTION
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
-t, --text
read in text mode (default)
The following three 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
-w, --warn
warn about improperly formatted checksum lines
--strict
with --check, exit non-zero for any invalid input
--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.
