Hi, [ *Simple response]* Think of what "sudo rm -R *" can do. It removes all files in your home directory - your downloads, your documents, music & videos and all changed settings of your daily used applications.
Think of what "sudo rm -R /" can do. Well, if you know that "/" in GNU/Linux indicates the root of the entire disk structure, you know what you are messing with The danger is that if these are your second or further commands (with sudo), you won't be prompted for password even! [*Advanced response]* A recent note I made after seeing a Google+ post which blew my earlier assumptions that this power of sudo/su is only unnecessarily hyped: Why sudo is dangerous?
