NAME¶

sha512sum - Print or check the SHA512 checksums

SYNOPSIS¶

sha512sum [-c|--check] [-w|--warn] [--status] [--quiet] [--ignore-missing] [--strict] [--tag] [-t|--text] [-z|--zero] [-h|--help] [-V|--version] [file]

DESCRIPTION¶

Print or check the SHA512 checksums

OPTIONS¶

-c, --check

read checksums from the FILEs and check them

-w, --warn

warn about improperly formatted checksum lines

--status

don't output anything, status code shows success

--quiet

don't print OK for each successfully verified file

--ignore-missing

don't fail or report status for missing files

--strict

exit non-zero for improperly formatted checksum lines

--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

-h, --help

Print help

-V, --version

Print version

VERSION¶

v(uutils coreutils) 0.9.0

EXAMPLES¶

Calculate the SHA512 checksum for one or more files:

sha512sum path/to/file1 path/to/file2 ...

Calculate and save the list of SHA512 checksums to a file:

sha512sum path/to/file1 path/to/file2 ... > path/to/file.sha512

Calculate a SHA512 checksum from `stdin`:

command | sha512sum

Read a file of SHA512 checksums and filenames and verify all files have matching checksums:

sha512sum [-c|--check] path/to/file.sha512

Only show a message for missing files or when verification fails:

sha512sum [-c|--check] --quiet path/to/file.sha512

Only show a message when verification fails, ignoring missing files:

sha512sum --ignore-missing [-c|--check] --quiet path/to/file.sha512

Check a known SHA512 checksum of a file:

echo known_sha512_checksum_of_the_file path/to/file | sha512sum [-c|--check]
