Deleted .DS_Store files, Now my drive is EMPTY! Help!

Question

In Mac's Terminal application I used a command I found on Adobe's website to delete .DS_Store files because I thought I had some corrupt ones. The command was to delete all of them on the entire machine. Since they are not critical files, I figured what the heck. Well, maybe I typed something wrong. I know Terminal is very touchy (now I know). But all of the files on my external drive are gone. When I double-click the drive icon, the window shows 0 items. Can anyone tell me what went wrong and how to undo the problem. I think all the files are still on the drive, there's just no directory to view them - so it says there's 0 files. Help please!
Here's the commands I entered in Terminal. Note that the first line is the command that was supposed to erase the .DS_Store files. The second line asked for my password. When I entered it, it may have deleted the files, but then it gave me no new command prompt. So everything you see from the "sudo" on is things I entered trying to get a new prompt. So I think that's where I screwed something up.

By the way, the Adobe article that showed how to delete the .DS_Store files (in case that helps) is at: http://kb2.adobe.com/cps/168/tn_16831.html

I just did the same exact thing (but recovered!). I hope you didn't empty your recycle bin/trash yet! Your library information is there - get it out!
The instructions on the web are a bit obtuse - what you need to do is delete ONLY the "iTunes Music" folder within the default iTunes location; I deleted the ENTIRE "iTunes" folder and saw exactly what you do now. You need to restore the "iTunes Library.itl" and "iTunes Music Library.xml" files, and you'll be back in business.
Not sure how you'll recover if you can't get those files back...
