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