模拟击键 [英] Simulate key press in bash

问题描述

我有一个问题，我有一个非常简单的脚本，它可以循环启动另一个二进制文件，看起来像这样:

I have a question, Im having very simple script that starts anpther binary file in loop it looka like this:

for (( i=0; \\$i <= 5; i++ )) ; do 
 test.sh 
done

现在的问题是，每次执行后，test.sh都会询问我是否要覆盖日志，例如您是否要覆盖日志?[是/否]"

Now problem is that after each execution test.sh asks me if I want to to override log something Like "Do you want to override log? [Y/n]"

在该提示出现之后，脚本暂停并且迭代停止，直到我手动按Y，然后继续直到出现另一个提示为止.

After that prompt appears scripts pauses and iteration is stopped until I manually press Y and that it continues until another prompt appears.

要使过程自动化，我可以模拟按下"Y"按钮吗?

To automate process can I simulate pressing "Y" button?

推荐答案

我相信，如果您的test.sh脚本未将其标准输入用于其他目的，则使用yes可能就足够了:yes将产生一个无限大的默认情况下y的行流，或者您将其作为参数传递的任何其他字符串.每次test.sh检查用户输入时，它应该消耗该输入的一行并继续执行其操作.

I believe using yes might be enough if your test.sh script doesn't use its standard input for other purposes : yes will produce an infinite stream of lines of y by default, or any other string you pass it as a parameter. Each time the test.sh checks for user input, it should consume a line of that input and carry on with its actions.

使用yes Y，您可以为test.sh脚本提供更多的Y脚本:

Using yes Y, you could provide your test.sh script with more Y than it will ever need :

yes Y | test.sh

要在循环中使用它，您最好将其通过管道传递到循环的stdin而不是test.sh调用:

To use it with your loop, you might as well pipe it to the loop's stdin rather than to the test.sh invocation :

yes Y | for (( i=0; i <= 5; i++ )) ; do 
 test.sh 
done
