Simulate "ENTER" key press in shell script
提问by Zack
I want to automate the run of the ./configurecommand. When I normally run it, every time I have to press enter. I want to run this command from a shell script and I don't want it to wait for a user to press enter at each prompt for path. How do I achieve this ? I am using Ubuntu machine with bash shell. Thanks.
我想自动化./configure命令的运行。当我正常运行它时，每次我都必须按回车键。我想从 shell 脚本运行这个命令，我不希望它等待用户在每个提示输入路径时按 Enter。我如何实现这一目标？我正在使用带有 bash shell 的 Ubuntu 机器。谢谢。

Note : I tried the below link but it does not work. How to simulate two consecutive ENTER key presses for a command in a bash script?
注意：我尝试了下面的链接，但它不起作用。 如何在 bash 脚本中为一个命令模拟两次连续的 ENTER 键按下？
I have used "yes" command already but when I run ./configure there are multiple prompts which are more than two. When I use "yes", it just supplies argument to the first prompt only
我已经使用了“是”命令，但是当我运行 ./configure 时，会出现多个超过两个的提示。当我使用时"yes"，它只为第一个提示提供参数

yescommand can be used here (with just 2 enter key)
yes可以在此处使用命令（只需 2 个回车键）
yes " " | head -2 | ./configure
In general, this should work.
一般来说，这应该有效。
yes | ./configure
