System( ) | Executes an operating system command |
System( command )
Executes a command in the underlying operating system. If the command itself executes but is in error, and if there exists a priority n +101 (where n is the current priority), the execution of the dialplan will continue at that priority level.
This application is very similar to the trySystem( ) application, except that it will return -1 if it is unable to execute the system command, whereas the trySystem( ) application will always return .
