Often in Pen Testing courses it is stressed that to be a good Pen Tester one should have very good command  line knowledge. It is amazing what you could do with command line skills.

We have had the opportunity to see some of it with the 3 part Webcast series last year and the Ed, Paul and Hal have continued it on the command line kung fu blog ...

I would suggest that everyone should check that out because it has some very cool stuff and I take this opportunity to thank them for the good work for benefit of the security community.

Thanks
