• switchTo ?(-b|-n|-p|-s)? ?value?
Switch to the specified application. The application can be designated using one of the following options:

Option	Description
-b	bundle identifier
-n	name or path of application
-p	process identifier (integer)
-s	application signature (four-char code)

If the application is not already running, the command will launch it (provided it is available on the machine). The use of application signatures is deprecated: the -s option is maintained for legacy reasons but should be avoided.
If the command is used with no arguments, it activates (that is to say brings to the front) Alpha itself.
If the command is invoked with only the value argument, the option -n is assumed.
