NAME
       sha256sum - compute and check SHA256 message digest

SYNOPSIS
       sha256sum [OPTION] [FILE]...

DESCRIPTION
       Print  or check SHA256 (256-bit) checksums.  With no FILE, or when FILE
       is -, read standard input.

       -b, --binary
	      read in binary mode

       -c, --check
	      read SHA256 sums from the FILEs and check them

       -t, --text
	      read in text mode (default)

   The following two options are useful only when verifying checksums:
       --status
	      dont 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 program.  The default mode is
       to print a line with checksum, a character  indicating  type  (*  for
       binary,	 for text), and name for each FILE.
