# top
> Display dynamic real-time information about running processes.
> More information: <https://manned.org/top>.
- Start `top`:
`top`
- Do not show any idle or zombie processes:
`top {{[-i|--idle-toggle]}}`
- Show only processes owned by given user:
`top {{[-u|--filter-only-euser]}} {{username}}`
- Sort processes by a field:
`top {{[-o|--sort-override]}} {{field_name}}`
- Show the individual threads of a given process:
`top {{[-Hp|--threads-show --pid]}} {{process_id}}`
- Show only the processes with the given PID(s), passed as a comma-separated list. (Normally you wouldn't know PIDs off hand. This example picks the PIDs from the process name):
`top {{[-p|--pid]}} $(pgrep {{[-d|--delimiter]}} ',' {{process_name}})`
- Display help about interactive commands:
`<?>`
