Where is the command log file? (I think that's what it is called)

Question

Someone recently used my computer and may have used some files or put some things on my computer that I would prefer they had not. Is there a file or system command that I can use to determine what has and has not been done on my computer? Or a file that tells me everything that has occured on my computer over a certain period of time?
Thanks for any assistance.

If you did not let them use the password of the admin user, they should not have been able to change the system.
For future use: set up a guest account on your computer without any system access and let others use that. If someone has your user id and your password, yes, then they could mess with the system. Never let anyone else use your admin account.
edit: if you are indeed afraid that someone may have installed some sort of keylogging program, then do an "erase and install" from your install dvds.
Then, remember to create a guest account before letting anyone else use your computer. You might also do as some do and create two accounts for yourself, one with admin access and one without and then login to the one without and just use login as admin user id and password when you need to change the system.
