# 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
