Execute the command on the remote host.

 public  void setAppend(boolean append) 
{
        this.append = append;
}

Determines if the output is appended to the file given in setOutput. Default is false, that is, overwrite the file.

 public  void setCommand(String command) 
{
        this.command = command;
}

Sets the command to execute on the remote host.

 public  void setCommandResource(String f) 
{
        this.commandResource = new FileResource(new File(f));
}

Sets a commandResource from a file

 public  void setOutput(File output) 
{
        outputFile = output;
}

If used, stores the output of the command to the given file.

 public  void setOutputproperty(String property) 
{
        outputProperty = property;
}

If set, the output of the command will be stored in the given property.

 public  void setTimeout(long timeout) 
{
        maxwait = timeout;
}

The connection can be dropped after a specified number of milliseconds. This is sometimes useful when a connection may be flaky. Default is 0, which means "wait forever".
