Name

System() — Executes an operating system command

Synopsis

    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 0.
