Welcome to the extended "Shell Out" section of the book. In deciding to join me here, you have identified yourself as one of the bold and curious explorers who really want to know their Linux systems. Sure, it is possible to work day in and day out with your Linux system and rarely use the command line, but the command line is power. Your reward for continuing to this next level will be a deeper understanding of your system and the power to make it do whatever you want.
