bash 在expect{exp_continue}之后继续脚本

continue script after expect{exp_continue}

提问by user788171

I have bash code that looks like the following:

我有如下所示的 bash 代码：

/usr/bin/expect -c '
    spawn python Tools/python/install.py
    expect {
        -nocase "password:" {
            send "$env(PASS)\r"
            exp_continue
        }
    }
    interact
'

This code seems to work except for the fact that after it submits the passwords, it hangs. After this block of code, there is more code I want to execute in my script. Is there a way to get expect to drop me back into the bash script to continue execution of lines below this block of code?

这段代码似乎可以工作，除了在提交密码后它挂起的事实。在这段代码之后，我想在我的脚本中执行更多代码。有没有办法让我回到 bash 脚本中以继续执行此代码块下方的行？

I'm guessing the interactcommand is biting you. From the man page:

我猜这个interact命令正在咬你。从手册页：

interactgives control of the current process to the user, so that keystrokes are sent to the current process, and the stdout and stderr of the current process are returned.

交互将当前进程的控制权交给用户，以便将击键发送到当前进程，并返回当前进程的 stdout 和 stderr。

I would try either of these:

我会尝试以下任一方法：

• Remove the interactcommand
• Issue the command in the background using &or screen

• 删除interact命令
• 使用&或在后台发出命令screen

Based on your comment, it looks like the former was what worked.

根据您的评论，看起来前者是有效的。
