Linux Operating System$]$ ps is a command that displays information about all processes currently

running in your system.

Read man page of ps command.

Enter the following commands: $(1)$ ps $$ef $|$ more and $(2)$ ps $$aux $|$ more. Both of these will result in

displaying a long list of processes.

Identify what processes are started when the system is booted, and what processes are started later

on$.$ For each process, find out who owns it$,$ what code it is running, and how much CPU$/$memory it has

used.

Now, store the details of all processes owned by root in a file called root$-$processes$-1,$ and all

processes owned by you in a file called my$-$processes$-1.$ Next, restart your system, and create similar

files, root$-$processes$-2$ and my$-$processes$-2.$ Compare root$-$processes$-2$ with root$-$processes$-2,$ and

my$-$processes$-1$ with my$-$processes$-1.$ Explain the differences between the two.

NB$.$ The following Linux command is used to store the details of all processes owned by the root user

in a file called root$\_$processes.txt

ps $-$U root $-$u root u $>$ root$\_$processes.txt
