我正在尝试对文件夹进行采样以查看是否已创建所需的文件，因此我使用以下代码块每60秒对其进行采样：
public static String command(Node node , long durationInSec, String command)
throws Exception {
RemoteCommandStrategy strategy = new RemoteCommandStrategy(node);
Future<String> future = strategy.apply(new com.indeni.automation.terminal.Command(command) , durationInSec);
return future.get();
}
其中node是我的远程服务器，我正在使用的命令是：
"watch -n 60 find /usr/share/indeni/insight/ -name \"alert.csv\"";
但是当我执行此操作时，出现以下错误：
java.util.concurrent.ExecutionException: com.sun.mail.iap.CommandFailedException: Error opening terminal: unknown.
