# sha512sum

|
|
> Calculate SHA512 cryptographic checksums.

> More information: <https://www.gnu.org/software/coreutils/manual/html_node/sha2-utilities.html>.
|
|
|
|
- Calculate the SHA512 checksum for a file:
|
|
|
|
`sha512sum {{path/to/file}}`
|
|
|
|
- Calculate SHA512 checksums for multiple 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}}`
|
|
|
|
- Read a file of SHA512 sums and verify all files have matching checksums:
|
|
|
|
`sha512sum --check {{path/to/file.sha512}}`
|
|
|
|
- Only show a message for files for which verification fails:
|
|
|
|
`sha512sum --check --quiet {{path/to/file.sha512}}`
