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

     --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 pro-
     gram.  The default mode is to print a line with checksum,  a
     character  indicating  type  (`*' for binary, ` ' for text),
     and name for each FILE.
