Checking System Process

To view a list of process in the system, we can use a handy command top or ps

For Details, please refer to Lab 2.

top

In the terminal, type

$ top

Thetop program will show the current processes live, just like the Windows task manager :0).

Consult man page for more options.

ps

Another handy tool for checking the processes. In the terminal, we use

$ ps

This will show the current processes created by the user in this terminal. Of course, this is not quite useful. We can view all the processes in the system by:

$ ps aux

The command is followed by an argument, aux

Argument	Description
a	Shows processes from all users
u	Displays the owner of the process
x	Also shows the processes other than the terminal

For more information, you are welcome to look at the man page.
