在模拟bash脚本ENTER键preSS [英] Simulating ENTER keypress in bash script

问题描述

我创建运行一些命令一个非常简单的bash脚本。
这些命令的人需要在运行时用户输入。即它要求用户你想等等等等等等？，我想简单地发送一个回车键preSS这使该脚本就会被完全自动化。

我将不必等待运行时输入或任何东西，它足以只发送键preSS和输入缓冲区将处理剩下的。

解决方案

 回声-ne的'\\ n'| ＆LT; yourfinecommandhere＆GT;
 

或采取呼应隐含换行的优势产生（感谢马辛）

 回声| ＆LT; yourfinecommandhere＆GT;
 

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.

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.

解决方案

echo -ne '\n' | <yourfinecommandhere>

or taking advantage of the implicit newline that echo generates (thanks Marcin)

echo | <yourfinecommandhere>
