The
ptree utility prints the process trees
containing the specified
pids or
users, with child processes indented from
their respective parent processes. An argument of all digits is taken to be a
process-ID, otherwise it is assumed to be a user login name. The default is
all processes.
The following options are supported:
-
-
-a- All. Print all processes, including children of process 0.
-
-
-c- Contracts. Print process contract memberships in addition to parent-child
relationships. See process(4). This option
implies the
-a option.
-
-
-z
zone- Zones. Print only processes in the specified
zone. Each zone
ID can be specified as either a zone name or
a numerical zone ID.
This option is only useful when executed in the global zone.
The following operands are supported:
-
-
- pid
- Process-id or a list of process-ids.
ptree also accepts
/proc/nnn
as a process-id, so the shell expansion
/proc/* can be used to specify all
processes in the system.
-
-
- user
- Username or list of usernames. Processes whose effective user IDs match
those given are displayed.
-
-
- /proc/*
- process files
The
ptree utility exits 0 on success,
and >0 if an error occurs.
- Example 1
- Using ptree
The following example prints the process tree (including children of process
0) for processes which match the command name
ssh:
$ ptree -a `pgrep ssh`
1 /sbin/init

569150 /usr/lib/ssh/sshd
569157 /usr/lib/ssh/sshd

569171 bash
569173 /bin/ksh
