cmd | : | string |
timeout | : | {0, posint} |
Returns: list
Synopsis: The System passes the argument cmd to the underlying operating system. If the optional timeout argument is specified, Darwin waits for time seconds. If a time out occurs, it returns [-1, (Timeout)], otherwise it returns a list consisting of the value returned by the operating system and the output generated by cmd.
Examples:
> TimedCallSystem('finger hallett@inf.ethz.ch', 20);
