|
> Calculate BLAKE2 cryptographic checksums.
|
|
> More information: <https://www.gnu.org/software/coreutils/b2sum>.
|
|
|
|
- Calculate the BLAKE2 checksum for a file:
|
|
|
|
`b2sum {{path/to/file}}`
|
|
|
|
- Calculate BLAKE2 checksums for multiple files:
|
|
|
|
`b2sum {{path/to/file1}} {{path/to/file2}}`
|
|
|
|
- Calculate the BLAKE2 checksum from stdin:
|
|
|
|
`{{some_command}} | b2sum`
|
|
|
|
- Read a file of BLAKE2 sums and filenames and verify all files have matching checksums:
|
|
|
|
`b2sum --check {{path/to/file.b2}}`
|
|
|
|
- Only show a message for missing files or when verification fails:
|
|
|
|
`b2sum --check --quiet {{path/to/file.b2}}`
|
|
|
|
- Only show a message for files for which verification fails, ignoring missing files:
|
|
|
|
`b2sum --ignore-missing --check --quiet {{path/to/file.b2}}`
