Do you know that Linux makes a process whenever the program is launched? This process called a container of information in running the program?


Below are the list that you can in managing a Linux process: 

  • Know which processes are running
  • Know how many processes you are using on your Linux system  
  • Spot a particular process to know what you will
  • Determine or change the level of priority combine with that process
  • Terminate the process if it’s misbehaving

The commands you will encounter below should be used by Command Line Interface (CLI). What you need is just to open a terminal window to have access. It's one of the powerful and most flexible.

1. top 

This command provides an information on the process that exits, remember that the first part is the overview of the position. While the second part is set-up in columns, provides details or content in every process with a unique reference number, priority, resource usage, and status.

2. htop 

The command htop it's like top, but smarter. Why? because in htop the details presented are in a clearer format where you can choose your particular process by using the arrow keys, act on it by using F1, F2, etc, where you can find in the htop display. Htop is great because it is always applicable to the Linux system.

There could also be another installation before using it 

sudo apt-get install htop 

if you’re using Ubuntu or Debian.

3. ps

The command ps is for listing running process, it will list htop and top all process even if it's  active or inactive. To get a useful information, you need to identify just one or other option. Remember that ps command will list all the processing running in your system.

4. pstree

The pstree command used so that you can display processes of the tree diagram, where it also shows a relationship that exists. Do you know that every process is generated by another process in linux. One important thing is when you alter something in the parent process, the child process will be affected too

5. who 

This command displays a list of those users that are currently login into your Linux system. You are capable of managing all the processes you would like. It can also be used to provide a simpler information, because if other users logged in before the terminating process it could be very important.
