无业游民条款:从键盘/stdin读取行

问题描述

所以，我有一个带有代码的Vagrantfile:

And so, I have a Vagrantfile with code:

VAGRANTFILE_API_VERSION = "2"
Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|
...
  config.vm.provision "shell", inline: 'echo "Read line:" && read t && echo "$t"'
...
end

当我执行vagrant provision时，我得到的输出是:

and when I execute vagrant provision i have that output:

$ vagrant provision
...
==> default: Running provisioner: shell...
    default: Running: inline script
==> default: Read line:
==> default: exit

这不建议在键盘/标准输入框中输入一行！

that is no suggest enter a line from keyboard/stdin!

在配置外壳脚本执行过程中，如何从键盘/stdin读取行?

What I should do for reading line from keyboard/stdin during provision shell script execution?

推荐答案

我这样做是在我的Vagrantfile中

I do it this way, in my Vagrantfile

puts "Input text: "
input = STDIN.gets.chomp

config.vm.provision :shell, inline: "echo #{input}"
