Deprecated

since 1.2. delegate to Execute instead.

Executes a given command if the os platform is appropriate.

As of Ant 1.2, this class is no longer the implementation of Ant's <exec> task - it is considered to be dead code by the Ant developers and is unmaintained. Don't use it.

Doc from java.lang.Thread.run.

This method is run by the thread when it executes. Subclasses of Thread may override this method.

This method is not intended to be invoked directly. If this thread is a platform thread created with a Runnable task then invoking this method will invoke the task's run method. If this thread is a virtual thread then invoking this method directly does nothing.
