How to clear "last" command in terminal?

[domenator]

I've searched Google and been unable to find an answer to this. I use terminal heavily and when I use the command "last" I get hundreds of my logins over the course of the past 3 years. This is really obnoxious to scroll through when I'm looking for when my kids logged in a day ago. Does anyone know a command to reset this so the next time i enter "last" I will have a nice fresh blank log? Appreciate any help.

What version of OS X? The man page

http://developer.apple.com/mac/library/DOCUMENTATION/Darwin/Reference/ManPages/man5/wtmp.5.html

Says that the /var/log/wtmp file isn't used anymore... but usually you could handle this by touching that file...

sudo touch /var/log/wtmp

You do know you can limit the number of entries returned? eg

last -5

this will give the last 5 logins.

You can also add a username eg

last -5 domenator

this will show the last 5 logins for the user domenator.

'man last' for more info

ty ty. I was using the man pages form OnyX for last, and for some reason last wasn't coming up there. Idk why I didn't think to just use man pages from terminal. Silly me.
