In Linux, the concept of “process” refers to a running instance of a program. Each process has its own set of resources, such as memory and CPU time, and is identified by a unique process ID (PID). Checking processes is essential for system monitoring, troubleshooting, and performance optimization.
There are several commands available for checking processes in Linux. The most commonly used command is “ps”, which provides a snapshot of the currently running processes. Other useful commands include “top”, which shows a dynamic view of the system’s processes, and “pstree”, which displays a hierarchical tree of processes.
