This series of articles helps you learn Linux system administration tasks. The topics mirror those of the Linux Professional Institute Certification (LPIC) level 1 (LPIC-1) exams. You can use the articles to prepare for certification, or just to learn about Linux.
There are two exams for LPIC-1 certification: exam 101 and exam 102, and you must pass both to attain LPIC-1 certification. Each exam has several topics, and each topic has several objectives. This series of articles covers one objective per article.
The material in these articles corresponds to the April 2009 objectives for exam 101 and exam 102. You should always refer to the objectives for the definitive requirements.
This roadmap is in progress; as we complete articles, we add them to the roadmap. In the meantime, though, you can find earlier versions of similar material, supporting previous LPIC-1 objectives prior to April 2009, in our LPI certification exam-prep tutorials (login required).
Note: New material will be added over the coming months as it becomes available. Build your own feed as explained in the sidebar, or check back here for updates.
