.Sh SYNOPSIS
.Nm
.Op Fl gvxdDqn
.Op Ar action Op Ar service
.Sh DESCRIPTION
The
.Nm
utility may be used to start, stop, and restart the system services which
are described in the
.Pa /Library/StartupItems/
and
.Pa /System/Library/StartupItems/
paths.
.Pp
The optional
.Ar action
argument specifies which action
.Nm
performs on the startup items.  The optional
.Ar service
argument specifies which startup items to perform the action on.  If no
.Ar service
is specified, all startup items will be acted on; otherwise, only the item providing the
.Ar service ,
any items it requires, or any items that depend on it will be acted on.
.Pp
During boot
.Nm
is invoked by
.Nm rc
(see rc(8)) and is responsible for
starting all startup items in an order that satisfies each item's
requirements.
.Sh ACTIONS

start all items, or start the item that provides the specified
.Ar service
and all items providing services it requires.
.It Nm stop
stop all items, or stop the item that provides the specified
.Ar service
and all items that depend on it.
.It Nm restart
restart all items, or restart the item providing the specified
.Ar service .

is made,

examines the exit status of the startup item scripts to determine the success or failure of the services provided by that script.
