# sha224sum > Calculate SHA224 cryptographic checksums. > More information: . - Calculate the SHA224 checksum for one or more files: `sha224sum {{path/to/file1 path/to/file2 ...}}` - Calculate and save the list of SHA224 checksums to a file: `sha224sum {{path/to/file1 path/to/file2 ...}} > {{path/to/file.sha224}}` - Calculate a SHA224 checksum from `stdin`: `{{command}} | sha224sum` - Read a file of SHA224 sums and filenames and verify all files have matching checksums: `sha224sum --check {{path/to/file.sha224}}` - Only show a message for missing files or when verification fails: `sha224sum --check --quiet {{path/to/file.sha224}}` - Only show a message when verification fails, ignoring missing files: `sha224sum --ignore-missing --check --quiet {{path/to/file.sha224}}`
