Overview

Sha512sum util implement by go.

Usage: sha512sum [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(default)
-c, --check   read SHA512 sums from the FILEs and check them
-t, --text    read in text mode
Note: there is no difference between text and binary mode option.

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 formated checksum lines

    --help     show help and exit
    --version  show version 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.
