			==pstree==



			pstree is a small, command line (i.e., all-text mode) program that displays the processes (i.e., executing instances of programs) on the system in the form of a tree diagram. It differs from the much more commonly used (and more complex) ps program in a number of respects, including that the latter shows the processes in a list rather than a tree diagram but provides more detailed information about them.

			Tree Diagrams

			A tree diagram is a way of showing the ancestral relationships among processes (or other entities) by connecting them with short lines that indicate for each process the process from which it originated (i.e., its parent) and any processes that it created (i.e., its children). This type of diagram differs from the usual image of a tree in that the root is at the top and the branches point downwards.

			Similar inverted tree diagrams are commonly used to illustrate the hierarchical filesystems of Linux and other Unix-like operating systems, which begin with the root directory (represented by a forward slash) off from which branch the second tier directories such as /bin, /boot, /etc, /home, /mount and /sbin.

			One of the advantages of pstree as compared with ps is that it makes it easier to terminate a series of related processes (i.e., all of the descendants of a particular process). This is because pstree makes it immediately clear which process is the parent, and all that is necessary is to terminate the parent in order to extinguish all of its descendant processes. That is, it is not necessary to manually search through a list to find and individually terminate each process as would be necessary using ps. The kill command is commonly used to terminate a crashed or otherwise misbehaving program or process.

			Syntax

			The basic syntax for pstree is:

			pstree [options] [pid or username]

			The square brackets indicate that the items in them are optional. If pstree is used without any options or arguments, that is, by typing

			pstree

			and then pressing the ENTER key, the result is a tree diagram that shows all of the processes currently on the system.
