So, this one day I was working on my computer late at night. I didn't know that my friend was accessing it remotely (ssh) and before going to sleep I ran "shutdown" command. After that I received a SMS instantly from him saying "Dude, what the f*** !! ". Even though the guy is really nice but as you can see these accidental shutdowns or reboots can cause a lot of trouble :P. Well linuxers, using Molly-guard you can prevent such things too.
