在bash脚本中模拟输入按键

I've created a really simple bash script that runs a few commands. one of these commands needs user input during runtime. i.e it asks the user "do you want to blah blah blah?", I want to simply send an enter keypress to this so that the script will be completely automated.

我创建了一个非常简单的bash脚本，它运行一些命令。其中一个命令在运行时需要用户输入。我。它会问用户“你想说什么?”，我只想向它发送一个enter keypress，以便脚本将完全自动化。

I won't have to wait for the input or anything during runtime, its enough to just send the keypress and the input buffer will handle the rest.

在运行时，我不需要等待输入或任何东西，它只需要发送按键和输入缓冲区就可以处理剩下的部分。
