Learn Linux, 101: A roadmap for LPIC-1 About this series 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.
