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}}
