# Top

### Usage

* f  - customize top show options
* 'N' - to sort the list by process id
* 'P' - to sort the process list by cpu usage.
* 'T' - to sort by the running time.
* 'Mm' - to sort by the memory
* 1 - show all cpus usage
* -d/d - delay seconds `top -d 2`
* -c/c - show it will display absolute path of running process.
* -u - `top -u mysql`
* save top results `top -n 1 -b > top-output.txt`
* -r/r  - renice pid

```
Fields Management for window 1:Def, whose current sort field is %CPU
   Navigate with Up/Dn, Right selects for move then <Enter> or Left commits,
   'd' or <Space> toggles display, 's' sets sort.  Use 'q' or <Esc> to end!
