com.sun.faban.harness.agent.CmdAgentImpl

CmdAgentImpl is the class that runs remote commands for the CmdService This implementation provides a robust means of running remote commands. All error messages from the remote commands are logged to the error log, which should help in debugging. The user is encouraged not to run huge shell scripts using this interface as the debugging advantages will be lost. Rather, try and break up the task to running Java/native apps as far as possible and use shell scripts sparingly. If the shell scripts spit out periodic status messages indicating the position in its execution cycle, this will aid in debugging.

It implements the CmdAgent interface; see the CmdAgent.java file for its description.
Application-defined exceptions.
