Top running process in Linux by CPU and RAM , you are around Linux System Administration or even casually using it and want to know whats taking up most of your system resources, below is the command.

  PID  PPID CMD                         %MEM %CPU

Why we are discussing this is because covering the very usual things for Linux for hackers ends with not much of knowledge. We thought better equip with real-life usage which will take us closer to understanding Linux.

We will take a bit more to understand the above command.

-o argument lets you decide the output of ps command
pid, ppid are for process id and name associated with cmd
%cpu , %mem for CPU and RAM utilisation
--sort to sort by CPU or RAM usage and -%mem for descending order of memory usage

We will discuss more on Linux in further post to make your terminal life easier.
