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.
