# sha384sum > Calculate SHA384 cryptographic checksums. > More information: . - Calculate the SHA384 checksum for one or more 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}}` - Calculate a SHA384 checksum from `stdin`: `{{command}} | sha384sum` - Read a file of SHA384 sums and filenames 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 when verification fails, ignoring missing files: `sha384sum --ignore-missing --check --quiet {{path/to/file.sha384}}`
