Options

--binary, -b

read in binary mode

--check, -c

read hashsums from the FILEs and check them

--tag

create a BSD-style checksum

--text, -t

read in text mode (default)

--quiet, -q

don't print OK for each successfully verified file

--status, -s

don't output anything, status code shows success

--strict

exit non-zero for improperly formatted checksum lines

--ignore-missing

don't fail or report status for missing files

--warn, -w

warn about improperly formatted checksum lines

--zero, -z

end each output line with NUL, not newline

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 sums and filenames and verify all files have matching checksums:

sha512sum --check {{path/to/file.sha512}}

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

sha512sum --check --quiet {{path/to/file.sha512}}

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

sha512sum --ignore-missing --check --quiet {{path/to/file.sha512}}
