Print or check SHA512 (512-bit) checksums. With no FILE, or when
FILE is -, read standard input.
read in binary mode
read SHA512 sums from the FILEs and check them
--tag create a BSD-style checksum
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
don't output anything, status code shows success
exit non-zero for improperly formatted checksum lines
warn about improperly formatted checksum lines
--help display this help and exit
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.
