Monitoring running processes is a critical task in Unix-based systems. To effectively manage system resources and ensure smooth operation, system administrators and users often need to check if a specific process is running.
There are several methods to check if a process is running in Unix. One common approach is to use the `ps` command. `ps` provides a snapshot of the currently running processes and allows users to filter the output based on various criteria, such as process name, user, and resource utilization.
