|
- Calculate the SHA1 checksum for one or more files:
|
2014-07-22 10:56:22 +01:00
|
|
|
|
2023-05-19 10:34:36 +01:00
|
|
|
`sha1sum {{path/to/file1 path/to/file2 ...}}`
|

|
|
|
|
2023-05-19 10:34:36 +01:00
|
|
|
- Calculate and save the list of SHA1 checksums to a file:
|
2016-01-20 11:45:42 +00:00
|
|
|
|
2023-05-19 10:34:36 +01:00
|
|
|
`sha1sum {{path/to/file1 path/to/file2 ...}} > {{path/to/file.sha1}}`
|

|
|
|
|
2023-05-19 10:34:36 +01:00
|
|
|
- Calculate a SHA1 checksum from `stdin`:

|
|
|
|
2023-05-20 03:11:11 +01:00
|
|
|
`{{command}} | sha1sum`
|

|
|
|
|
2023-05-19 10:34:36 +01:00
|
|
|
- Read a file of SHA1 sums and filenames and verify all files have matching checksums:
|
2014-07-22 10:56:22 +01:00
|
|
|
|
2021-09-03 20:31:29 +01:00
|
|
|
`sha1sum --check {{path/to/file.sha1}}`
|
2020-12-18 12:47:34 +00:00
|
|
|
|
2022-03-28 15:21:41 +01:00
|
|
|
- Only show a message for missing files or when verification fails:
|
2020-12-18 12:47:34 +00:00
|
|
|
|
2021-09-03 20:31:29 +01:00
|
|
|
`sha1sum --check --quiet {{path/to/file.sha1}}`
|
2022-03-28 15:21:41 +01:00
|
|
|
|
2023-05-19 10:34:36 +01:00
|
|
|
- Only show a message when verification fails, ignoring missing files:
|
2022-03-28 15:21:41 +01:00
|
|
|
|
|
|
|
|
`sha1sum --ignore-missing --check --quiet {{path/to/file.sha1}}`
|
