This article helps you prepare for Objective 103.6 in Topic 103 of the Linux Professional Institute’s Junior Level Administration (LPIC-1) exam 101. The objective has a weight of 2.

Prerequisites

To get the most from the articles in this series, you should have a basic knowledge of Linux and a working Linux system on which you can practice the commands covered in this article. Sometimes different versions of a program will format output differently, so your results may not always look exactly like the listings and figures shown here. The results in the examples shown here were obtained on a Ubuntu 9.10 (Karmic Koala) distribution. This article builds on the concepts discussed in the previous article “Learn Linux 101: Create, monitor, and kill processes.”
