SHA224SUM(1)                  User Commands                 SHA224SUM(1)

NAME         top

       sha224sum - compute and check SHA224 message digest

SYNOPSIS         top

       sha224sum [OPTION]... [FILE]...

DESCRIPTION         top

       Print or check SHA224 (224-bit) checksums.

       With no FILE, or when FILE is -, read standard input.

       -b, --binary
              read in binary mode

       -c, --check
              read checksums from the FILEs and check them

       --tag  create a BSD-style checksum

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

       -z, --zero
              end each output line with NUL, not newline, and disable
              file name escaping

   The following five options are useful only when verifying checksums:
       --ignore-missing
              don't fail or report status for missing files

       --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 RFC 3874.  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.

       There is no difference between binary mode and text mode on GNU
       systems.
