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 SHA512 sums from the FILEs and check them
-t, --text
read in text mode (default)
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 pro-
gram. The default mode is to print a line with checksum, a
character indicating type (`*' for binary, ` ' for text),
and name for each FILE.
