SHA512SUM(1) User Commands 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 checksums from the FILEs and check them --tag create a BSD-style checksum -t, --text read in text mode (default) -z, --zero end each output line with NUL, not newline, and disable file name escaping The following five options are useful only when verifying checksums: --ignore-missing don't fail or report status for missing files --quiet don't print OK for each successfully verified file --status don't output anything, status code shows success --strict exit non-zero for improperly formatted checksum lines -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 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. AUTHOR Written by Ulrich Drepper, Scott Miller, and David Madore.
