Simulating ENTER keypress in bash script
提问by tobbr
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 脚本来运行一些命令。这些命令之一在运行时需要用户输入。即它询问用户“你想等等等等吗？”，我想简单地向这个发送一个输入按键，这样脚本将完全自动化。
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.
我不必在运行时等待输入或任何东西，只需发送按键就足够了，输入缓冲区将处理其余部分。

echo -ne '\n' | <yourfinecommandhere>
or taking advantage of the implicit newline that echo generates (thanks Marcin)
或利用 echo 生成的隐式换行符（感谢 Marcin）
echo | <yourfinecommandhere>
Now we can simply use the --skoption:
现在我们可以简单地使用该--sk选项：
--sk,--skip-keypressDon't wait for a keypress after each test
--sk,--skip-keypress不要在每次测试后等待按键
i.e. sudo rkhunter --sk --checkall
IE sudo rkhunter --sk --checkall
