# sha256sum
|
|
|
|
> Calculate SHA256 cryptographic checksums.
|
|
|
|
- Calculate the SHA256 checksum for file(s) or files in a directory, one checksum per file:
|
|
|
|
`sha256sum {{filename1}}`
|
|
`sha256sum {{filename1}} {{filename2}}`
|
|
`sha256sum {{directory/\*}}`
|
|
|
|
- Read a file of SHA256 sums and verify all files have matching checksums:
|
|
|
|
`sha256sum -c {{filename.sha256}}`
