Calls 'system()' function, passing through all arguments unchanged.

This should be used when calling possibly mutative or destructive functions (e.g. unlink() and other file system functions) so that can be suppressed if the simulation mode is enabled.

Parameters

$exec: The shell command to execute. Parameters should already be escaped.

Return value

The result code from system(): 0 == success.
