bash - 用户名/密码结构的BASH脚本

Question

我想使用ncat编写一个简单的bash脚本，以打开与ISP及其端口的连接。

第一个命令是:

nc address port

完成此操作后，首先提示我提供一个用户名。我必须按ENTER键，然后提示我提供密码，然后必须再次按ENTER键。

之后，我要打开一个终端进程窗口。谁能指出我有足够的资源来进行这种脚本编写？

我已经知道用户名和密码了，但是我不太确定如何解决必须先提供用户名然后按Enter的事实。我也不确定如何打开新的终端程序。

提前致谢!

查看期望脚本
Expect

例:

# Assume $remote_server, $my_user_id, $my_password, and $my_command were read in earlier
# in the script.
# Open a telnet session to a remote server, and wait for a username prompt.
spawn telnet $remote_server
expect "username:"
# Send the username, and then wait for a password prompt.
send "$my_user_id\r"
expect "password:"
# Send the password, and then wait for a shell prompt.
send "$my_password\r"
expect "%"
# Send the prebuilt command, and then wait for another shell prompt.
send "$my_command\r"
expect "%"
# Capture the results of the command into a variable. This can be displayed, or written to disk.
set results $expect_out(buffer)
# Exit the telnet session, and wait for a special end-of-file character.
send "exit\r"
expect eof
