sha224sum

Calculate SHA224 cryptographic checksums. More information: https://www.gnu.org/software/coreutils/manual/html_node/sha2-utilities.html.

• 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 checksums 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}}

• Check a known SHA224 checksum of a file:

echo {{known_sha224_checksum_of_the_file}} {{path/to/file}} | sha224sum --check
