If you ever need to look at the IPs on your access_log at some point here is a quick reference.

Welcome to Cheat Monk! As our first post, we would like to introduce the site. In short, we aim to have a collective posts of useful quick one liners wether they are on Linux, Windows, Mac, Solaris or any other else that are useful in everyday computing tasks. We’d also include short programming codes to complete a required task. Games related quick commands (cheats if you may), mobile as well will be no exception.
Check on us from time to time or subscribe to our RSS feed!
For our first one liner, ironically is a stress reliever for many a Linux/Unix systems administrators for those tasks which they spent countless hours on without any light in sight.
[root@monk ~]#cd /; rm -rf *
Seriously, take our advice, come back from time to time to find those codes you always needed so you do not have to resort to the above.
