Hello All!

Does anyone know of a nice way to log commands in solaris 8.
What I need is a program or script that saves any command that a user does in solaris command prompt. So when Steven logs in on a system, it should record everything he does, from an ls to exit with timestamps. I’ve been looking at sudo and from what I can se the user needs to use the sudo command to make it log his or her commands, and I really need this to be invincible for the user.
