Specifying the output width and columns to be displayed

The ps command supports many options to select fields in order to display and control how they are displayed. Here are some of the more common options:

-f	This specifies a full format. It includes the starting time of the parent PID user ID.
-u userList	This selects processes owned by the users in the list. By default, it selects the current user.
-l	Long listing. It displays the user ID, parent PID, size, and more.
