NAME    [Toc]    [Back]

       pstree - display a tree of processes

SYNOPSIS    [Toc]    [Back]

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

DESCRIPTION    [Toc]    [Back]

       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.

	   init-+-getty
		|-getty
		|-getty
		`-getty

       becomes

	   init---4*[getty]

OPTIONS    [Toc]    [Back]

       -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.

       -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 doesn't 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
	      available.

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