sha512sum

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)

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

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 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.
