Desktop disappeared after reboot. Help!!

[rissarai]

While trying to enable my Microsoft Office 2008 to allow me to enter a new code I pasted a rm command into the terminal, as directed by someone in a forum. I think it may have wiped out my desktop because now the entire desktop is gone.
Will Diskwarrior help me with this or is it a lost cause?
All my music and photo files are fine, it is just everything that was on the desktop, which was a lot.
Please help.

Check the trash bin?

I tried that. It is not in there, but thanks for trying to help.

I've been scourging the internet in an attempt to find something like that, but have had no success. I guess OS X doesn't really need a system restore type of thing, since it's so stable...but then when you have problems like this your S.O.L. unless you created a time-machine backup
