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.
