Congratulations; you've reached the end of "Basic administration". We hope that this tutorial has helped you to firm up your foundational Linux knowledge. Please join us in our next tutorial, "Intermediate administration," where we'll build on the foundation laid here, covering topics like the Linux permissions and ownership model, user account management, filesystem creation and mounting, and more. And remember, by continuing in this tutorial series, you'll prepare yourself to attain your LPIC Level 1 Certification from the Linux Professional Institute. Speaking of LPIC certification, if this is something you're interested in, then we recommend that you study the following resources, which augment the material covered in this tutorial:

There are a number of good regular expression resources on the Web. Here are a couple that we've found:

• Regular Expressions Reference

• Bash by example, Part 2: More bash programming fundamentals
• Bash by example, Part 3: Exploring the ebuild system

You can learn more about sed in the following developerWorks articles (Parts 1 and 2 will be good preparation for the LPIC Level 1 exam):

• Sed by example, Part 2: Taking further advantage of the UNIX text editor
• Sed by example, Part 3: Data crunching, sed style

To learn more about awk, read the following developerWorks articles:

• Awk by example, Part 1: Intro to the great language with the strange name

• Awk by example, Part 3: String functions and ... checkbooks?

We highly recommend the Technical FAQ by Linux Users, a 50-page in-depth list of frequently-asked Linux questions, along with detailed answers. The FAQ itself is in PDF (Adobe Acrobat) format. If you're a beginning or intermediate Linux user, you really owe it to yourself to check this FAQ out.

If you're not familiar with the vi editor, we strongly recommend that you check out Daniel's Vi intro -- the cheat sheet method tutorial. This tutorial will give you a gentle yet fast-paced introduction to this powerful text editor. Consider this must-read material if you don't know how to use vi.
