sha256sum

Calculate SHA256 cryptographic checksums.

More information.

• Calculate the SHA256 checksum for a file:

sha256sum {path/to/file}

• Calculate SHA256 checksums for multiple 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}

• Read a file of SHA256 sums 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 for files for which verification fails, ignoring missing files:

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