NAME

sha384sum - compute and check SHA384 message digest

SYNOPSIS

sha384sum [OPTION]... [FILE]...

DESCRIPTION

Print or check SHA384 (384-bit) checksums. With no FILE, or when FILE is -, read standard input.

-b, --binary: read in binary mode
-c, --check: read SHA384 sums from the FILEs and check them
-t, --text: read in text mode (default)
: Note: There is no difference between binary and text mode option on GNU system.

The following three options are useful only when verifying checksums:

--quiet: don't print OK for each successfully verified file
--status: don't output anything, status code shows success
-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 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 character indicating type (`*' for binary, ` ' for text), and name for each FILE.
