SHA512SUM(1)                     User Commands                    SHA512SUM(1)

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
       --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.
