sha224sum — compute and check SHA224 message digest
sha224sum [OPTION...] [FILE...]
Print or check SHA224 (224−bit) checksums.
With no FILE, or when FILE is −, read standard input.
−b, −−binaryread in binary mode
−c, −−checkread SHA224 sums from the FILEs and check them
−−tagcreate a BSD−style checksum
−t, −−textread in text mode (default)
−−quietdon't print OK for each successfully verified file
−−statusdon't output anything, status code shows success
−−strictexit non−zero for improperly formatted checksum lines
−w, −−warnwarn about improperly formatted checksum lines
−−helpdisplay this help and exit
−−versionoutput 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.
