sha224sum

Calculate SHA224 cryptographic checksums.

• Calculate the SHA224 checksum for a file:

sha224sum {{filename1}}

• Calculate SHA224 checksums for multiple files:

sha224sum {{filename1}} {{filename2}}

• Calculate and save the list of SHA224 checksums to a file:

sha224sum {{filename1}} {{filename2}} > {{filename.sha224}}

• Read a file of SHA224 sums and verify all files have matching checksums:

sha224sum --check {{filename.sha224}}

• Only show a message for files for which verification fails:

sha224sum --check --quiet {{filename.sha224}}
