.Sh NAME
.Nm jps
.Nd prints processes running in a jail
.Sh SYNOPSIS
.Nm
.Fl i
.Ar jail
.Nm 
.Ar jail
.Op Ar ps-options ...
.Sh DESCRIPTION
The 
.Nm 
utility prints out a list of the processes running in a given jail. When run 
with the
.Fl i
argument it just prints out the process ids. Otherwise it prints out a full
.Xr ps 1
type listing for the processes in the jail. The 
.Xr ps 1
formatting and other options are available for use.
.Sh OPTIONS
.Bl -tag -width ".Fl u Ar ps-options"
.It Fl i
Only print out the process ids.
.It Ar jail
Either a jail id (which is an integer) or a jail host name.
.It Ar ps-options
Formatting and other to be passed to 
.Xr ps 1
when listing processes in the jail.
.El
.Sh NOTES
It is possible to run two jails with the same host name.
.Nm
however always only prints out processes for one jail.
.Pp
The environment is purged properly before running 
.Xr ps 1
in the jail in order to prevent unwanted information from 
leaking into the jail.
.Pp
.Nm
needs a valid 
.Pa /dev/null
device in the jail. If it doesn't exit for some reason it is automatically 
created.
