# sha512sum

|
|
> Calculate SHA512 cryptographic checksums.

> More information: <https://www.gnu.org/software/coreutils/manual/html_node/sha2-utilities.html>.
|
|
|
|
- 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}}`
