This is a task from work which has been given to me but unfortunately they will not install any modules, none what soever and will not give me access to anything except to write this script.. ultimatly what it does is parses a logfile and useraccounts file and searches for certain strings such as times and usernames. I have never done perl before but yet I am being told to do this!

Sounds you either have to grow up, or find another job.
