Terminal commands with automator

Question

So I am not really used to scripts and the script language nor in automator, I only made a few apps with automator like resize picture and show/hide hidden files.
Now I am about to make an app which cleans my OS, I would like to run all these commands with one click, rather then copy pasting them into terminal one- by-one.
sudo rm -rf /private/var/log/*
sudo rm -rf /private/var/folders/
cd /private/var/tmp/; rm -rf TM*
cd ~/Library/Caches/; rm -rf ~/Library/Caches/*
this would clean my mac caches and logs, like i would run it every week as im a power user.
Please someone tell me how to put all these into automator and try to be detailed. Thanks for the support!

Answer 1

Thanks for both positive, useful and sarcastic responses. The main reason is why I want to do this is becasuse I use different browsers, and all the cache they make is 2-3GB/day, as I use the web the most.
I see the reason why NOT TO clear it and I do understand it, but after a week it is 10-15GB for me.
And no, there isnt anyone else using my Mac, and the logs which I would nuke at every start and only keep the last and updated logs. I only need the startup and boot log.
@barney-15E yes it would be fun though
So then, I wont do anythings, as it cannot be done the way I wanted. I'll keep using Onyx.
