As well as being a newbie to the security world i am a newbie to linux.which from what i read in a way go hand in hand.i know there is a "who is" command for linux but what about a "what is" i was told in a bbs that there is a what is command, but in my research i found no such command. so my question is, is there a command called "what is" and if so what things can be done with it and how do i use it? or was this person just trying to sound like a experianced user when he was no more then a newbie like myself? thanks for all replies.
