Objective 5: Create, Monitor, and Kill Processes
This Objective looks at the management of processes. Just as file management is a fundamental system administrator’s function, the management and control of processes is also essential for smooth system operation. In most cases, processes will live, execute, and die without intervention from the user because they are automatically managed by the kernel. However, there are times when a process will die for some unknown reason and need to be restarted. Or a process may “run wild” and consume system resources, requiring that it be terminated. You will also need to instruct running processes to perform operations, such as rereading a configuration file.
