Explanation / Answer

>The ps (i.e., process status) command is used to provide information about the currently running processes, including their process identification numbers (PIDs)
>The basic syntax of ps is
ps [options]
>When ps is used without any options, it sends to standard output, which is the display monitor by default, four items of information for at least two processes currently on the system: the shell and ps.
>A shell is a program that provides the traditional, text-only user interface in Unix-like operating systems for issuing commands and interacting with the system, and it is bash by default on Linux. ps itself is a process and it dies (i.e., is terminated) as soon as its output is displayed.
