As you read through this section and learn about these tools, I strongly encourage you to run the commands. You will also find some basic commands that you can run through in the online labs at http://gcgapremium.com/501labs/. A challenge many test takers have is that they don’t have a Linux system to play around with these commands. If you can’t enter them and see what they do, you might have trouble with even the easy questions. The online labs include labs you can use to create a virtual Linux environment on a Windows system.
