sha512sum — compute and check SHA512 message digest
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)
−−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.
