SHA384SUM(1) User Commands SHA384SUM(1)
sha384sum – compute and check SHA384 message digest
sha384sum [OPTION]… [FILE]…
Print or check SHA384 (384-bit) checksums.
With no FILE, or when FILE is -, read standard input.
read in binary mode
read SHA384 sums from the FILEs and check them
–tag create a BSD-style checksum
read in text mode (default)
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
warn about improperly formatted checksum lines
–help display this help and exit
output version information and exit
The sums are computed as described in FIPS-180-2. 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.
