关于相同有几篇文章,但我仍然无法使我期望的脚本正常工作.我的意图是使所有操作自动化,但保留用户输入的密码.因此,脚本包含3部分：

>自动登录
>给用户交互输入密码
>将控制权交还给Expect脚本以继续工作

所以我有将要生成的脚本,并且具有3个读取命令.第一个和最后一个应该由Expect填充,第二个我要输入我自己：

#!/bin/ksh
read user?User:
echo "Expect entered the username $user"
read pass?Password:
echo "User entered the password $pass"
read command?"Shell>"
echo "Expect entered the command $command"

我的期望脚本：

#!/usr/bin/expect
spawn ./some_script
expect User
send I-am-expect\r
expect Password
interact
expect Shell
send I-am-expect-again

不幸的是,在我输入密码后,脚本无法继续运行并处于交互模式：

[root@localhost ~]# ./my-expect
spawn ./some_script
User:I-am-expect
Expect entered the username I-am-expect
Password:i am user
User entered the password i am user
Shell>

最后,当我在“ Shell”上输入内容并按[ENTER]时,期望退出并显示错误：

Expect entered the command
expect: spawn id exp4 not open
    while executing
"expect Shell"
    (file "./my-expect" line 7)
[root@localhost ~]#

我希望对此问题做出任何解释或解决.我正在使用期望版本5.45

解决方法:

您可以自己读取(expect_user)用户密码,然后将其发送给生成的程序.例如：

[STEP 101] # cat foo.exp
proc expect_prompt {} \
{
    global spawn_id
    expect -re {bash-[.0-9]+(#|\$)}
}

spawn ssh -t 127.0.0.1 bash --noprofile --norc
expect "password: "

stty -echo
expect_user -timeout 3600 -re "(.*)\[\r\n]"
stty echo
send "$expect_out(1,string)\r"

expect_prompt
send "exit\r"
expect eof
[STEP 102] # expect foo.exp
spawn ssh -t 127.0.0.1 bash --noprofile --norc
root@127.0.0.1's password:
bash-4.3# exit
exit
Connection to 127.0.0.1 closed.
[STEP 103] #
