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.

read in binary mode
read checksums from the FILEs and check them
create a BSD-style checksum
read in text mode (default)
end each output line with NUL, not newline, and disable file name escaping

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
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.

There is no difference between binary mode and text mode on GNU systems.
