How would I move Safari Cache back to original folder? I've deleted the RAM Disk but com.apple.Safari isn't in Library/Cache after reboot.

@nischu7 if you don't mind answering, the
/dev/rdisk2 size of 1024 MB is ~50% the size of the
ram://2097152. That seems to be consistent for various different file systems. Is there a short explanation the size difference, or can you recommend what I might read up on to better understand what's going on?

Hi I'm wondering if I put this script in my ~/Library/StartupItems directory, will it run at startup?

To create a startup script in OS X you'll have to build an Automator app.
Start Automator. With CMD + N to you'll create a new workflow. In the first dialogue you choose for creating an app.
Then you'll search for 'shell'. Drag it. Paste this script. Save it - probably to your app folder.
In System Settings go to Users and groups. Click on Log-on objects and add your recently created app. That would do it.
