sha384sum — compute and check SHA384 message digest
Calculate the SHA384 checksum for a file:
Calculate SHA384 checksums for multiple files:
sha384sum filename1 filename2
Read a file of SHA384 sums and verify all files have matching checksums:
sha384sum -c filename.sha384
sha384sum [OPTION]... [FILE]...
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
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 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.
Note: There is no difference between binary mode and text mode on GNU systems.
