Ⓘ Note: This tutorial also works for any Linux Distribution. If you are a beginner, you should read this Command Line Tutorial. Basic command-line knowledge (cat, grep, less, more, etc).How to work with processes in foreground and background.How to start, stop and kill processes and jobs.Understanding the importance of monitoring processes in Linux.Basic Command-line commands for working with processes in Linux.The first process is initiated after the Kernel is loaded in memory on boot, which in turn, starts other processes, and so on. It is essential to have a good understanding of how processes and their hierarchies are generated because this information is vital for monitoring and troubleshooting your system. We will be using the command line instead of graphical tools, because in many cases, specially when troubleshooting, they won’t be available. This is because every time our system needs to start a task or a user issues a command, a program is run and one or more processes are generated. In this tutorial, we’ll walk you through one of the most important aspects of any operating system, the processes.
