ps command

One of the core aspects of Linux system administration and performance monitoring involves keeping an eye on how processes utilize system resources, particularly CPU usage. In this blog post, we'll delve into the nuances of using the ps command in Linux to parse and calculate cumulative CPU usage of running processes. We'll start with a Q&A format to address some common queries, follow up with more examples and explanations, and cap things off with an executable script that illustrates the practical application. A1: The ps (Process Status) command in Linux is a powerful utility that shows information concerning a selection of running processes. It's widely used for monitoring the processes running on a system.

Monitoring running processes is a fundamental task in managing Linux systems. Whether you're a system administrator tracking the performance of servers, a developer debugging an application, or just curious about what's running on your machine, the ps command is an essential tool in any Linux user's arsenal. In this blog post, we'll explore how to use ps to view currently running processes and guide you through installing it on various Linux distributions using different package managers. ps stands for "Process Status." It is used in Unix-like operating systems to display information about active processes on a system. This command can show a snapshot of processes running at the moment you run the command.

When managing a Linux system, whether it’s monitoring a critical server or simply keeping your personal computer’s resources in check, understanding and utilizing the ps command (process status) is critical. This tool is designed to list the currently-running processes on a system, providing insights that can help both novice users and experienced administrators make informed decisions regarding system health and performance. The ps command is a traditional Unix/Linux utility that displays information about active processes. By default, without any arguments, ps will show all processes running under the current shell.
