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 {{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}}
