这种情况会使channel.getExitStatus（）返回1

Question

private String test(String command){
    channel = sesConnection.openChannel("exec");
    ((ChannelExec) channel).setCommand(command);
    BufferedReader br = 
    new BufferedReader(new InputStreamReader(channel.getInputStream()));
    InputStream error = ((ChannelExec) channel).getErrStream();
    channel.connect();
    StringBuffer outputstream = new StringBuffer();
    String msg = null;
    while ((msg = br.readLine()) != null) {
           outputstream.append(msg);            
    }
    System.out.println("Channel exit status:" + channel.getExitStatus());
}

Answer 1

• 当command完成时（＆＃34; exec＆＃34;频道关闭）并返回退出代码1.
• 当频道甚至无法打开时（通常command不是有效命令时）。
