SHA224SUM(1) User Commands SHA224SUM(1)
NAME
 sha224sum - compute and check SHA224 message digest
SYNOPSIS
 sha224sum [OPTION]... [FILE]...
DESCRIPTION
 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 SHA224 sums 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 in-
 put 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.
 Note: There is no difference between binary mode and text mode on GNU
 systems.
