pstree

NAME

       pstree - display a tree of processes

SYNOPSIS

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

DESCRIPTION

       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

       -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.

       -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.

       -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.

       -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  '##tresc##33%8'  and  left  with
              echo -e '##tresc##33%@'

       -V     Display version information.
