sha256sum

Calculate SHA256 cryptographic checksums.

  • Calculate the SHA256 checksum for a file:

sha256sum {{filename1}}

  • Calculate SHA256 checksums for multiple files:

sha256sum {{filename1}} {{filename2}}

  • Calculate and save the list of SHA256 checksums to a file:

sha256sum {{filename1}} {{filename2}} > {{filename.sha256}}

  • Read a file of SHA256 sums and verify all files have matching checksums:

sha256sum --check {{filename.sha256}}

  • Only show a message for files for which verification fails:

sha256sum --check --quiet {{filename.sha256}}
