SYNOPSIS

DESCRIPTION

13       The  ptree  utility  prints  the process trees containing the specified
14       pids or users, with child processes indented from their respective par‐
15       ent  processes.  An argument of all digits is taken to be a process-ID,
16       otherwise it is assumed to be a user login name.  The  default  is  all
17       processes.
18

OPTIONS

20       The following options are supported:
21
22       -a         All. Print all processes, including children of process 0.
23
24
25       -c         Contracts. Print process contract memberships in addition to
26                  parent-child  relationships.  See  process(4).  This  option
27                  implies the -a option.
28
29
30       -z zone    Zones. Print only processes in the specified zone. Each zone
31                  ID can be specified as either a zone  name  or  a  numerical
32                  zone ID.
33
34                  This option is only useful when executed in the global zone.

36

OPERANDS

38       The following operands are supported:
39
40       pid     Process-id  or  a  list  of  process-ids.  ptree  also  accepts
41               /proc/nnn as a process-id, so the shell expansion  /proc/*  can
42               be used to specify all processes in the system.
43
44
45       user    Username  or  list of usernames. Processes whose effective user
46               IDs match those given are displayed.

EXAMPLES

51
52
53       The following example prints the process tree  (including  children  of
54       process 0) for processes which match the command name ssh:
55
56
57         $ ptree -a `pgrep ssh`
58                 1     /sbin/init
