我正在尝试连接到FTP服务器。在交互模式下，我没问题。
Connected to datatransfer.cj.com.
220 Commission Junction FTP Server. All transfers are logged.
Name (datatransfer.cj.com:gwendal): <mysuperuser>
331 User name okay, need password for mysuperuser.
Password: <interactive password input>
230-WARNING: This server is for exchange of business data with Commission Junction only.
230- Any attempt to upload data that has not been approved by Commission Junction
230- will result in termination of your ftp account. Access restrictions apply.
230- The IP address of this host name may change without notice.
230 User mysuperuser logged in from xx.xx.xx.xx
但是我需要在shell脚本中使用此ftp，因此我必须使用非交互模式。

我真的不知道发生了什么。密码包含%，但我认为这不是大问题。我也试图逃避它，同样的问题。
当然，我完全确定密码正确。
预先感谢您的帮助。
