expect的问题

fucj

以下是我用的expect的脚本
#!/usr/bin/expect
set user [lindex $argv0]
set ipadd [lindex $argv 1]
spawn -necho ssh $usr@@ipadd
expect "Enter*"
send "password\r"
expect eof
exit

我再执行./expect.sh x x
请问为什么我用这个脚本ssh登陆成功后,再输入任何命令都没有返回信息。

expect不是这样用的，我给你一段FTP的脚本，差不多的，楼主可以参考

########        Start FTP       ########
set FTPPROMPT "ftp>"

}
