Listing processes in LinuxTo list processes in Linux, use one of the five commands: ps, top, htop, atop, and pstree. Each command offers different detail and output formats. For instance, ps provides a momentary view of all processes, while top and htop dynamically sort them by CPU usage...
The /proc directory contains information about currently running processes as well as some kernel parameters. o /sys This directory is similar to /proc in that it provides a device and system interface. You’ll read more about /sys in Chapter 3. o /sbin The place for system executables. ...

Step 2 – How To Use ps to List Processes topandhtopprovide a dashboard interface to view running processes similar to a graphical task manager. A dashboard interface can provide an overview, but usually does not return directly actionable output. For this, Linux provides another standard ...
There are several ways to automatically configure networks in Linux-based systems. The most widely used option on desktops and notebooks is NetworkManager. Othe...
During Linux system startup, the very first process to launch is the `init` process. Consequently, it typically holds the PID of 1. The `init` process serves as the master process, from which all other processes are eventually derived. Unlike regular processes, the `init` process is essenti...
The `service` command is another utility that allows you to manage daemons and other services in Linux, including starting, restarting, and stopping them. To get a list of all services using the `service` command, execute: service --status-all ...
Services or daemons are Linux programs that run in the background. System administrators must understand how to manage services to maintain their server’s functionality and performance. The commands to list services differ depending on the Linux init system. Systemd service listing usessystemctl, wh...
Processes read data from input streams and write data to output streams. Streams are very flexible. For example, the source of an input stream can be a file, a device, a terminal, or even the output stream from another process. 我们将使用cat命令简要探索Unix的输入和输出(I/O)。
Lastly, we’ll look at the lsns and ls commands and see how we can use them to get more information about namespaces. 2. What Is a Namespace? In Linux, a namespace is a feature that allows processes to use the system resources they need but separately from other processes. A namespac...
