Description: Listing processes means displaying the processes currently running on the system. This command is fundamental for operating system management, as it allows users and administrators to obtain a clear view of the tasks being carried out at any given moment. In Unix-like operating systems, listing processes is commonly done using commands like ‘ps’, ‘top’, or ‘htop’. These commands provide detailed information about each process, including its identifier (PID), status, CPU and memory usage, and runtime. The ability to list processes is crucial for troubleshooting, as it helps identify processes that consume excessive resources or are in an undesirable state. Additionally, it facilitates task management, allowing users to terminate problematic processes or monitor system performance in real-time. In summary, listing processes is an essential tool for any user looking to maintain effective control over their working environment in operating systems.
