SystemStarter -- Start, stop, and restart system services
SystemStarter [-gvxdDqn] [action [service]]
The SystemStarter utility may be used to start, stop, and restart the
system services which are described in the /Library/StartupItems/ and
The optional action argument specifies which action SystemStarter per-
forms on the startup items. The optional service argument specifies
which startup items to perform the action on. If no service is speci-
fied, all startup items will be acted on; otherwise, only the item pro-
viding the service, any items it requires, or any items that depend on it
will be acted on.
During boot SystemStarter is invoked by rc (see rc(8)) and is responsible
for starting all startup items in an order that satisfies each item's
start start all items, or start the item that provides the specified
service and all items providing services it requires.
stop stop all items, or stop the item that provides the specified
service and all items that depend on it.
restart restart all items, or restart the item providing the specified
-g graphical startup
-v verbose (text mode) startup
-x safe mode startup (only run Apple-provided items)
-r keep running after last startup item completes, in graphical
-d print debugging output
-D print debugging output and dependencies
-q be quiet (disable debugging output)
-n don't actually perform action on items (no-run mode)
Unless an explicit call to ConsoleMessage is made, SystemStarter examines
the exit status of the startup item scripts to determine the success or
failure of the services provided by that script.
In Darwin it is preferable to create custom startup items than to modify
rc, and at some point SystemStarter may entirely encompass the role of
/Library/StartupItems/ User-installed startup items.
/System/Library/StartupItems/ System-provided startup items.
The SystemStarter utility appeared in Darwin 1.0
SystemStarter was extended in Darwin 6.0 to support partial startup and
