If you are an avid seedbox user, here is another option for automatic uploads to google drive.
There are many ways of achieving this, including a cronjob.
I like this option, as it only runs rclone when a torrent completes.

Using inotifywait to watch for file system events, we look out for primarily the ‘move’ event.
When your torrent completes, it moves the completed torrent into the completed folder.
When this event takes place, when then execute rcopy.sh

Setup rclone and scripts

rscreen.sh

rwait.sh

rcopy.sh

Permissions and PATH

Once you have setup the 3 scripts, make them executable

Permissions

If ~/bin is not in your path, then add it and reload your shell

Edit Path

Finally you run the main script in a cronjob

Finalize and run in the background

Screen session
