ptree \- print process trees
.SH SYNOPSIS

.LP

\fB/usr/bin/ptree\fR [\fB-a\fR] [\fB-c\fR] [\fB-z\fR \fIzone\fR] [\fIpid\fR | \fIuser\fR]...
.fi
.SH DESCRIPTION
.sp
.LP
The \fBptree\fR utility prints the process trees containing the specified \fIpid\fRs or \fIuser\fRs, 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.
.SH OPTIONS
.sp
.LP
The following options are supported:
.sp
.ne 2
.mk
.na
\fB\fB-a\fR\fR
.ad
.RS 11n
.rt
All. Print all processes, including system processes.
.RE

.sp
.ne 2
.mk
.na
\fB\fB-c\fR\fR
.ad
.RS 11n
.rt
Contracts. Print process contract memberships in addition to parent-child relationships. See \fBprocess\fR(5). This option implies the \fB-a\fR option. 
.RE

.sp
.ne 2
.mk
.na
\fB\fB-z\fR \fIzone\fR\fR
.ad
.RS 11n
.rt
Zones. Print only processes in the specified \fIzone\fR. Each zone \fBID\fR can be specified as either a zone name or a numerical zone \fBID\fR.
.sp
This option is only useful when executed in the global zone.

The following operands are supported:
.sp
.ne 2
.mk
.na
\fB\fIpid\fR\fR
.ad
.RS 8n
.rt
Process-id or a list of process-ids. \fBptree\fR also accepts \fB/proc/\fR\fInnn\fR as a process-id, so the shell expansion \fB/proc/*\fR can be used to specify all processes in the system.
.RE

.sp
.ne 2
.mk
.na
\fB\fIuser\fR\fR
.ad
.RS 8n
