I have an Ubuntu 9.10 netbook. It has always run great. Two days ago, I was running as root for a while (~30), and when I moved back to my user account (only other account on this machine), all the commands in ~/bin stopped working.
If I try ls, it comes up with "cannot execute binary file". Same with ln, mv, mkdir, clear, cp, etc. They all run as root (which makes sense, different files), but I have no idea why this happened. I don't want to stay as root to move around easily. Any idea?
