Class NativeExecutableCommand

java.lang.Object

com.maverick.sshd.platform.ExecutableCommand

com.maverick.sshd.platform.NativeExecutableCommand

public class NativeExecutableCommand
extends ExecutableCommand

A further extension of the ExecutableCommand that provides the ability to execute a native process. Caution should be taken with this current implementation as no processing of EOL is provided and results may vary on different platforms. It is recommended that only automated clients use this feature due to the many differences in user terminals which may cause problems with command output not performing as expected.
