NAME
SystemStarter -- Start, stop, and restart system services SYNOPSIS
SystemStarter [-gvxdDqn] [action [service]] DESCRIPTION
The SystemStarter utility may be used to start, stop, and restart the system services which are described in the /Library/StartupItems/ and /System/Library/StartupItems/ paths. The optional action argument specifies which action SystemStarter performs on the startup items. The optional service argument specifies which startup items to perform the action on. If no service is specified, 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 requirements. ACTIONS
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 service. OPTIONS
-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 startup only -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) NOTES
Unless an explicit call to ConsoleMessage is made, SystemStarter examines the exit status of the startup item scripts to determine the suc- cess 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 rc. FILES
/Library/StartupItems/ User-installed startup items. /System/Library/StartupItems/ System-provided startup items. SEE ALSO

NAME
queue - Create and manipulate queue objects SYNOPSIS
package require Tcl 8.2 package require struct ?1.2.1? queueName option ?arg arg ...? queueName clear queueName destroy queueName get ?count? queueName peek ?count? queueName put item ?item ...? queueName size DESCRIPTION
The ::struct::queue command creates a new queue object with an associated global Tcl command whose name is queueName. This command may be used to invoke various operations on the queue. It has the following general form: queueName option ?arg arg ...? Option and the args determine the exact behavior of the command. The following commands are possible for queue objects: queueName clear Remove all items from the queue. queueName destroy Destroy the queue, including its storage space and associated command. queueName get ?count? Return the front count items of the queue and remove them from the queue. If count is not specified, it defaults to 1. If count is 1, the result is a simple string; otherwise, it is a list. If specified, count must be greater than or equal to 1. If there are no items in the queue, this command will return count empty strings. queueName peek ?count? Return the front count items of the queue, without removing them from the queue. If count is not specified, it defaults to 1. If count is 1, the result is a simple string; otherwise, it is a list. If specified, count must be greater than or equal to 1. If there are no items in the queue, this command will return count empty strings. queueName put item ?item ...? Put the item or items specified into the queue. If more than one item is given, they will be added in the order they are listed. queueName size Return the number of items in the queue. KEYWORDS
