|
|
- Calculate the SHA1 checksum for one or more files:
|
||
|
|
|
||
|
|
`shasum {{path/to/file1 path/to/file2 ...}}`
|
||
|
|
|
||
|
|
- Calculate the SHA checksum for one or more files with the specified algorithm:
|
||
|
|
|
||
|
|
`shasum --algorithm {{1|224|256|384|512|512224|512256}} {{path/to/file1 path/to/file2 ...}}`
|
||
|
|
|
||
|
|
- Calculate a SHA1 checksum from `stdin`:
|
||
|
|
|
||
|
|
`{{command}} | shasum`
|
||
|
|
|
||
|
|
- Calculate and save the list of SHA256 checksums to a file:
|
||
|
|
|
||
|
|
`shasum --algorithm 256 {{path/to/file1 path/to/file2 ...}} > {{path/to/file.sha256}}`
|
||
|
|
|
||
|
|
- Read a file of SHA checksums and filenames and verify all files have matching checksums (the algorithm will be automatically detected):
|
||
|
|
|
||
|
|
`shasum --check {{path/to/file}}`
|
||
|
|
|
||
|
|
- Only show a message for missing files or when verification fails:
|
||
|
|
|
||
|
|
`shasum --check --quiet {{path/to/file}}`
|
||
|
|
|
||
|
|
- Only show a message when verification fails, ignoring missing files:
|
||
|
|
|
||
|
|
`shasum --ignore-missing --check --quiet {{path/to/file}}`
|
||
|
|
|
||
|
|
- Check a known SHA checksum of a file:
|
||
|
|
|
||
|
|
`echo {{known_sha_checksum_of_the_file}} {{path/to/file}} | shasum --check`
|
