SHA512SUM(1)

NAME
sha512sum - compute and check SHA512 message digest

SYNOPSIS
sha512sum [OPTION] [FILE]...

DESCRIPTION

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

-t, --text
    read in text mode (default)

  The following two options are useful only when verifying checksums:

--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.
