# sha512sum
> Calculate SHA512 cryptographic checksums.
> More information: <https://man.archlinux.org/man/sha512sum.1>.
- Calculate the SHA512 checksum for a file:
`sha512sum {{filename1}}`
- Calculate SHA512 checksums for multiple files:
`sha512sum {{filename1}} {{filename2}}`
- Calculate and save the list of SHA512 checksums to a file:
`sha512sum {{filename1}} {{filename2}} > {{filename.sha512}}`
- Read a file of SHA512 sums and verify all files have matching checksums:
`sha512sum --check {{filename.sha512}}`
- Only show a message for files for which verification fails:
`sha512sum --check --quiet {{filename.sha512}}`
