Every once in a while I find a command that I could have used a couple of days ago. You know the one. Remember that time when you were trying to do something like killing a process or unmounting a stubborn usb drive? That is what I'm talking about. Whenever I find myself needing these commands I can never find where I have written them down or what file I saved them to. So I though I would create a page where I can store them. I know other sites have more of the same thing but I think this page may end up being more of a notepad for me than a place to share. Anyway, I hope you find some of them as usefull as I have.
