|
|
- Calculate the SHA224 checksum for a file:
|
2014-07-22 10:56:22 +01:00
|
|
|
|
|
|
|
|
`sha224sum {{filename1}}`
|
2016-01-20 11:45:42 +00:00
|
|
|
|
|
|
|
|
- Calculate SHA224 checksums for multiple files:
|
|
|
|
|
|
2014-07-22 10:56:22 +01:00
|
|
|
`sha224sum {{filename1}} {{filename2}}`
|
|
|
|
|
|
2020-12-18 14:17:54 +00:00
|
|
|
- Calculate and save the list of SHA224 checksums to a file:
|
2020-12-18 14:14:04 +00:00
|
|
|
|
2020-12-23 00:19:24 +00:00
|
|
|
`sha224sum {{filename1}} {{filename2}} > {{filename.sha224}}`
|
2020-12-18 14:14:04 +00:00
|
|
|
|
2016-01-07 17:31:27 +00:00
|
|
|
- Read a file of SHA224 sums and verify all files have matching checksums:
|
2014-07-22 10:56:22 +01:00
|
|
|
|
2020-12-18 14:04:57 +00:00
|
|
|
`sha224sum --check {{filename.sha224}}`
|
2020-12-18 12:47:34 +00:00
|
|
|
|
2020-12-20 19:34:27 +00:00
|
|
|
- Only show a message for files for which verification fails:
|
2020-12-18 12:47:34 +00:00
|
|
|
|
2020-12-18 14:04:57 +00:00
|
|
|
`sha224sum --check --quiet {{filename.sha224}}`
|
