One of my worst errors was trying to find a function definition while I was coding on a c++ project. I managed to execute 'grep operator> *'. First I found it strange that the grep operation didn't return anything. Then I started opening my files, and they were suddenly all empty. It took a few minutes before I realized exactly what I had done... (Of course, I hadn't committed anything the previous 5 hours.)
