Usage

Simply type the following command:

Code: [Select]

gtopOR

Code: [Select]

nodejs /usr/local/bin/gtop
Sample outputs:


You can sort the process table by pressing the following keys:
1. Press p to sort by process ID (PID).
2. Press c to sort by CPU usage.
3. Press m to sort by memory usage.

So, now you can see the output of top command in a much fancier way!!
