I made an Alfred extension since my schedule is too erratic for a scheduled scrub. I figured I would share in case any Alfred user with Powerpack had a want/need for it.
The Alfred command is - scrub PoolName - to start it and - scrub -s PoolName - to terminate it. The extension is set to silent so you don't have to see terminal pop up. You can still see progress in the preference pane or time left in terminal.
Here is the download if you want it.
NOTE: The file is .alfredextension so if your browser adds ".txt" at the end of file name, just remove ".txt".
