       pstree - display a tree of processes

       pstree [-a] [-c] [-h|-Hpid] [-l] [-n] [-p] [-u] [-Z] [-A|-G|-U]
       pstree -V

       pstree shows running processes as a tree. The tree is rooted at	either
       pid or init if pid is omitted. If a user name is specified, all process
       trees rooted at processes owned by that user are shown.

       pstree visually merges identical branches by  putting  them  in	square
       brackets and prefixing them with the repetition count, e.g.




       Child  threads  of a process are found under the parent process and are
       shown with the process name in curly braces, e.g.


       If pstree is called as pstree.x11 then it will prompt the user  at  the
       end of the line to press return and will not return until that has hap
       pened. This is useful for when pstree is run in a xterminal.

       -a     Show command line arguments. If the command line of a process is
	      swapped out, that process is shown in parentheses. -a implicitly
	      disables compaction.

       -A     Use ASCII characters to draw the tree.

       -c     Disable compaction of identical subtrees. By  default,  subtrees
	      are compacted whenever possible.

       -G     Use VT100 line drawing characters.

       -h     Highlight the current process and its ancestors. This is a no-op
	      if the terminal doesnt support highlighting or if  neither  the
	      current  process	nor  any  of  its ancestors are in the subtree
	      being shown.

       -H     Like -h, but highlight the  specified  process  instead.	Unlike
	      with  -h,  pstree  fails	when  using  -H if highlighting is not

       -l     Display long lines. By default, lines are truncated to the  dis
	      play  width or 132 if output is sent to a non-tty or if the dis
	      play width is unknown.

       -n     Sort processes with the same ancestor by PID instead of by name.
	      (Numeric sort.)

       -p     Show  PIDs.  PIDs  are  shown  as decimal numbers in parentheses
	      after each process name. -p implicitly disables compaction.

       -u     Show uid transitions. Whenever the uid of a process differs from
	      the uid of its parent, the new uid is shown in parentheses after
	      the process name.

       -U     Use UTF-8 (Unicode) line drawing characters. Under Linux	1.1-54
	      and  above,  UTF-8  mode	is entered on the console with echo -e
	      \033%8 and left with echo -e \033%@

       -V     Display version information.

       -Z     (SELinux) Show security context for each process.

       /proc	 location of the proc file system

       Werner	  Almesberger	       Craig	 Small

       Some character sets may be incompatible with the VT100 characters.

       ps(1), top(1).
