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 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.

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