sha512sum: compute and check SHA512 message digest
sha512sum - compute and check SHA512 message digest
SYNOPSISsha512sum [,OPTION/]... [,FILE/]...
Print or check SHA512 (512-bit) checksums.
With no FILE, or when FILE is -, read standard input.
- -b, --binary
- read in binary mode
- -c, --check
- read SHA512 sums from the FILEs and check them
- create a BSD-style checksum
- -t, --text
- 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
- -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.
