Currently rclone check supports matching two file trees by sizes and hashes. This change adds support for SUM files produced by GNU utilities like sha1sum. Fixes #1005 Note: checksum by default checks, hashsum by default prints sums. New flag is named "--checkfile" but carries hash name. Summary of introduced command forms: ``` rclone check sums.sha1 remote:path --checkfile sha1 rclone checksum sha1 sums.sha1 remote:path rclone hashsum sha1 remote:path --checkfile sums.sha1 rclone sha1sum remote:path --checkfile sums.sha1 rclone md5sum remote:path --checkfile sums.md5 ```
