# sha384sum > Calculate SHA384 cryptographic checksums. > More information: . - Calculate the SHA384 checksum for a file: `sha384sum {{path/to/file}}` - Calculate SHA384 checksums for multiple files: `sha384sum {{path/to/file1}} {{path/to/file2}}` - Calculate and save the list of SHA384 checksums to a file: `sha384sum {{path/to/file1}} {{path/to/file2}} > {{path/to/file.sha384}}` - Read a file of SHA384 sums and verify all files have matching checksums: `sha384sum --check {{path/to/file.sha384}}` - Only show a message for missing files or when verification fails: `sha384sum --check --quiet {{path/to/file.sha384}}` - Only show a message for files for which verification fails, ignoring missing files: `sha384sum --ignore-missing --check --quiet {{path/to/file.sha384}}`
