为什么有些linux命令不能在Citrus中执行，比如PWD

Question

我是连接到Linux服务器使用SFTP协议使用柑橘FTP组件。文档中提供的以下命令执行良好。

<send endpoint="ftpClient">
  <message>
    <payload>
      <ftp:command>
        <ftp:signal>MKD</ftp:signal>
        <ftp:arguments>test</ftp:arguments>
      </ftp:command>
    </payload>
  </message>
</send> 

但是，当我提供另一个命令，如PWD，如下所示

<send endpoint="ftpClient">
      <message>
        <payload>
          <ftp:command>
            <ftp:signal>PWD</ftp:signal>
            <ftp:arguments></ftp:arguments>
          </ftp:command>
        </payload>
      </message>
    </send> 

我搞错了。但是当我使用SSH协议执行上面的命令时，该命令执行得很好。

<send endpoint="sftpClient">
  <message>
    <payload>
      <ftp:command>
        <ftp:signal>pwd</ftp:signal>
        <ftp:arguments></ftp:arguments>
      </ftp:command>
    </payload>
  </message>
</send>

我无法解决这个问题，另一件事是如何使用柑橘ftp组件在序列中执行两个命令，例如，例如:我想移动到一个特定的路径，并看到该路径中文件的大小，为此，我们必须首先使用"CD“命令，然后使用"ls -l”，如何使用柑橘实现这个目标。下面是错误的堆栈跟踪

您提供的错误信息与PWD信号无关。它失败了，因为在使用FTP客户端时，您发送的信号ls -ltr不是受支持的信号。

如果要列出服务器上带有FTP的文件，则需要使用LIST信号。

请不要混淆SSH和FTP命令和信号。当然，您也可以打开SSH会话，并使用ls启动列表文件命令。但是您需要使用Citrus SSH客户端。
