# sha256sum

|
> Calculate SHA256 cryptographic checksums.

|
|
|
|
- Calculate the SHA256 checksum for one or more files:
|
|
|
|
`sha256sum {{path/to/file1 path/to/file2 ...}}`
|
|
|
|
- Calculate and save the list of SHA256 checksums to a file:
|
|
|
|
`sha256sum {{path/to/file1 path/to/file2 ...}} > {{path/to/file.sha256}}`
|
|
|
|
- Calculate a SHA256 checksum from `stdin`:
|
|
|
|
`{{some_command}} | sha256sum`
|
|
|
|
- Read a file of SHA256 sums and filenames and verify all files have matching checksums:
|
|
|
|
`sha256sum --check {{path/to/file.sha256}}`
|
|
|
|
- Only show a message for missing files or when verification fails:
|
|
|
|
`sha256sum --check --quiet {{path/to/file.sha256}}`
|
|
|
|
- Only show a message when verification fails, ignoring missing files:
|
|
|
|
`sha256sum --ignore-missing --check --quiet {{path/to/file.sha256}}`
