General Info

top is a task manager program found in many Unix-like operating systems that displays information about CPU and memory utilization.

This shell script tries to emulate it, showing on screen stadistic information regarding system processes. These processes are top-down ordered with the CPU usage ratio, only showing top 'n' ones. If not specified, 'n' is set to 10. If specified value of 'n' is greater than the number of processes, then information about all of them are shown.
