sha224sum

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

• Calculate the SHA224 checksum for a file:

sha224sum {{path/to/file}}

• Calculate SHA224 checksums for multiple 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}}

• Read a file of SHA224 sums 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 for files for which verification fails, ignoring missing files:

sha224sum --ignore-missing --check --quiet {{path/to/file.sha224}}
