Monitoring running processes is a crucial aspect of system administration in Unix-based operating systems. To effectively manage and troubleshoot system resources, it is essential to have a clear understanding of the processes currently executing on the system. Unix provides several commands and utilities that allow users to check and manage running processes, enabling them to identify resource-intensive tasks, troubleshoot performance issues, and maintain system stability.
One of the most commonly used commands for checking running processes in Unix is “ps”. The “ps” command provides detailed information about active processes, including their process ID (PID), user ownership, CPU and memory usage, and command line arguments. It supports various options to filter and format the output, allowing users to customize the displayed information based on their specific needs.
