How to automatically hit Enter in bash script when asked?
提问by Ooker
I know that this question is answered many times, but I still can't figure out how to do it. Maybe it's because I don't know the correct keyword to search for.
我知道这个问题已经回答了很多次了，但我仍然不知道该怎么做。也许是因为我不知道要搜索的正确关键字。
Using
使用
echo -ne '\n' | enter
doesn't work. My code is:
不起作用。我的代码是：
#! /bin/bash
#Grub-customizer
sudo add-apt-repository ppa:danielrichter2007/grub-customizer
echo -ne '\n' | return
sudo apt-get update
sudo apt-get install grub-customizer

You're supposed to pipe the \ninto the command that's going to be receiving it (otherwise it won't ever see it!):
你应该通过管道\n输入将要接收它的命令（否则它永远不会看到它！）：
echo -ne '\n' | sudo add-apt-repository ppa:danielrichter2007/grub-customizer
echo -ne '\n' | sudo apt-get install grub-customizer
Now, the right solution here would instead be to use the -yflags instead:
现在，正确的解决方案是改用-y标志：
sudo add-apt-repository -y ppa:danielrichter2007/grub-customizer
sudo apt-get install -y grub-customizer
