.TH PTREE 1 "Sep 3, 2019"
.SH NAME
ptree \- print process trees
.SH SYNOPSIS
.nf
\fB/usr/bin/ptree\fR [\fB-a\fR] [\fB-c\fR] [\fB-s\fR \fIsvc\fR] [\fB-z\fR \fIzone\fR] [\fIpid\fR | \fIuser\fR]...
.fi
.SH DESCRIPTION
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
The following options are supported:
.sp
.ne 2
.na
\fB\fB-a\fR\fR
.ad
.RS 11n
All. Print all processes, including children of process 0.
.RE
.sp
.ne 2
.na
\fB\fB-c\fR\fR
.ad
.RS 11n
Contracts. Print process contract memberships and their associated SMF FMRIs,
in addition to parent-child relationships. See \fBprocess\fR(4).
This option implies the \fB-a\fR option.
.RE
.sp
.ne 2
.na
\fB\fB-s\fR \fIsvc\fR\fR
.ad
.RS 11n
Print only processes with an SMF service FMRI matching the argument. The FMRI
may be in truncated form (such as 'console-login'). This includes children
processes even if they are not members of the service contract.
See \fBprocess\fR(4).
.RE
.sp
.ne 2
.na
\fB\fB-z\fR \fIzone\fR\fR
.ad
.RS 11n
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.
.RE
.SH OPERANDS
The following operands are supported:
.sp
.ne 2
.na
\fB\fIpid\fR\fR
.ad
.RS 8n
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
.na
\fB\fIuser\fR\fR
.ad
.RS 8n
Username or list of usernames. Processes whose effective user IDs match those
given are displayed.
.RE
.SH EXAMPLES
\fBExample 1 \fRUsing ptree
.sp
.LP
The following example prints the process tree (including children of process 0)
for processes which match the command name \fBssh\fR:
.sp
.in +2
.nf
$ ptree -a `pgrep ssh`
1 /sbin/init
100909 /usr/lib/ssh/sshd
569150 /usr/lib/ssh/sshd
569157 /usr/lib/ssh/sshd
569159 -ksh
569171 bash
569173 /bin/ksh
569193 bash

.in -2

.SH EXIT STATUS
The following exit values are returned:
.sp
.ne 2
.na
\fB\fB0\fR\fR
.ad
.RS 12n
Successful operation.
.RE
