Be Careful W/ That Rm Command, Kids!
Okay, so how about I went to go delete some unessecary files on my HD, and ruined my linux and had to reinstall.
I'm in a directory of files that just so happens to have a /bin directory in it. Not really thinking about it, I type the following command, which I dare anyone to repeat-
rmdir -rf /bin/*
And there goes most of my operating system.... Good thing I keep most important files on a separate partition....
