Automator - Can it subtract?

[reclusivemonkey]

Hello Everyone,

I tried searching the forums, and google but didn't really find anything.

I am trying to create a fairly simple (IMHO) Automator Workflow; I want to get my disk space from df -l and create a png from Google charts API to stick on my desktop via Geektool. However I can't seem to work out how to do a simple

100-Disk Space Used=Disk Space Free

via Automator. I'm thinking it will be easier just to shell script it and run it via cron.

Anyone got any ideas where I should be looking in Automator?

That's not really what Automator's designed to do. You're right, it would be far easier as a shell script, so why not just do that? Automator isn't really going to accomplish that.

Done; it was a lot easier with a shell script.

I would of thought anything that deal with variables would allow you to do basic arithmetic with them. At least I learned something about Automator on the way.
