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)
Note: There is no difference between binary and text mode option on GNU system.

    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.
