NAME

6       pstree - display a tree of processes
7

SYNOPSIS

9       pstree [-a] [-c] [-h|-Hpid] [-l] [-n] [-p] [-u] [-Z] [-A|-G|-U]
10       [pid|user]
11       pstree -V
12

DESCRIPTION

14       pstree shows running processes as a tree. The tree is rooted at  either
15       pid or init if pid is omitted. If a user name is specified, all process
16       trees rooted at processes owned by that user are shown.
17
18       pstree visually merges identical branches by  putting  them  in  square
19       brackets and prefixing them with the repetition count, e.g.
20
21           init-+-getty
22                |-getty
23                |-getty
24                `-getty
25
26       becomes
27
28           init---4*[getty]
29
30
31       Child  threads  of a process are found under the parent process and are
32       shown with the process name in curly braces, e.g.
33
34           icecast2---13*[{icecast2}]
35
36
37       If pstree is called as pstree.x11 then it will prompt the user  at  the
38       end of the line to press return and will not return until that has hap‐
39       pened. This is useful for when pstree is run in a xterminal.

OPTIONS

43       -a     Show command line arguments. If the command line of a process is
44              swapped out, that process is shown in parentheses. -a implicitly
45              disables compaction.
46
47       -A     Use ASCII characters to draw the tree.
48
49       -c     Disable compaction of identical subtrees. By  default,  subtrees
50              are compacted whenever possible.
51
52       -G     Use VT100 line drawing characters.
53
54       -h     Highlight the current process and its ancestors. This is a no-op
55              if the terminal doesn't support highlighting or if  neither  the
56              current  process  nor  any  of  its ancestors are in the subtree
57              being shown.
58
59       -H     Like -h, but highlight the  specified  process  instead.  Unlike
60              with  -h,  pstree  fails  when  using  -H if highlighting is not
61              available.
62
63       -l     Display long lines. By default, lines are truncated to the  dis‐
64              play  width or 132 if output is sent to a non-tty or if the dis‐
65              play width is unknown.
66
67       -n     Sort processes with the same ancestor by PID instead of by name.
68              (Numeric sort.)
69
70       -p     Show  PIDs.  PIDs  are  shown  as decimal numbers in parentheses
71              after each process name. -p implicitly disables compaction.
72
73       -u     Show uid transitions. Whenever the uid of a process differs from
74              the uid of its parent, the new uid is shown in parentheses after
75              the process name.
76
77       -U     Use UTF-8 (Unicode) line drawing characters. Under Linux  1.1-54
78              and  above,  UTF-8  mode  is entered on the console with echo -e
79              '\033%8' and left with echo -e '\033%@'
80
81       -V     Display version information.
82
83       -Z     (SELinux) Show security context for each process.
