SHA512SUM(1)                    User Commands                   SHA512SUM(1)

NAME         top

       sha512sum - compute and check SHA512 message digest

SYNOPSIS         top

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

DESCRIPTION         top

       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:
              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

       -w, --warn
              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 space, a character indicating input
       mode ('*' for binary, ' ' for text or where binary is insignificant),
       and name for each FILE.
