top - display Linux tasks
The top program provides a dynamic real-time view of a running system. It can display system summary information as well as a list of tasks currently being managed by the Linux kernel. The types of system summary information shown and the types, order and size of information displayed for tasks are all user configurable and that configuration can be made persistent across restarts.
‘top’ gives the following information
1. Process ID
2. USER
3. Task Priority
4. Nice value of a task
5. Amount of virtual memory used by task
6. Resident size (non swapped physical memory used by task)
7. Amount of shared memory used by task
8. Process status(whether sleep or running)
9. CPU time (in Hundredths) and
10. Share of physical memory usage
11. Duration of the Task
12. Task/command name
