Calculate SHA256 cryptographic checksums. More information:

  • Calculate the SHA256 checksum for one or more files:

sha256sum {{path/to/file1 path/to/file2 ...}}

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

sha256sum {{path/to/file1 path/to/file2 ...}} > {{path/to/file.sha256}}

  • Calculate a SHA256 checksum from stdin:

{{command}} | sha256sum

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

sha256sum --check {{path/to/file.sha256}}

  • Only show a message for missing files or when verification fails:

sha256sum --check --quiet {{path/to/file.sha256}}

  • Only show a message when verification fails, ignoring missing files:

sha256sum --ignore-missing --check --quiet {{path/to/file.sha256}}
