在期望可以获取特定文本的同时发送命令 [英] Send command while expect can get specific text

问题描述

我在使用Expect时遇到一个问题. 我需要列出一些信息. 但是程序列出了10个项目，然后显示(更多...)并等待一个键 所以:

I Have one problem when i am using expect. I need to list some information. But the program list 10 items and then shows (More...) and waits a key So:

expect "More..."
send "\n"

但是该程序显示了更多的10行，然后再次执行，我可以跟踪需要执行多少次，但是列表变化很大.

But the program shows more 10 lines and does it again, i can track how many times i need to do that, but the list changes a lot.

有没有办法做类似的事情:

Is there a way to do something like:

while expect "More..." do
   send "\n"
done

我知道期望值会等待一个字符串，是否存在某种命中"命令?

I know the expect waits for a string, is there some kind of "hit" command?

谢谢

推荐答案

您要exp_continue和expect的块形式:

expect {
  "More..." {
    send "\n"
    exp_continue
  }
  "something else to expect for"
}
