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}}
