compute and check SHA224 message digest


Calculate the SHA224 checksum for a file

$ sha224sum [path/to/file]

Calculate SHA224 checksums for multiple files

$ sha224sum [path/to/file1] [path/to/file2]

Calculate and save the list of SHA224 checksums to a file

$ sha224sum [path/to/file1] [path/to/file2] > [path/to/file.sha224]

Read a file of SHA224 sums and verify all files have matching checksums

$ sha224sum --check [path/to/file.sha224]

Only show a message for files for which verification fails

$ sha224sum --check --quiet [path/to/file.sha224]


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


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


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:


don't fail or report status for missing files


don't print OK for each successfully verified file


don't output anything, status code shows success


exit non-zero for improperly formatted checksum lines

-w, --warn

warn about improperly formatted checksum lines


display this help and exit


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.

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