I recently had to work with a file, in VS Code, that had several empty lines I wanted to remove all at once.

最近，我不得不使用VS Code中的文件，其中有几个空行，我想一次将其全部删除。

We’re talking about 700+ empty lines with some text in between, and I didn’t want to do this manually.

我们谈论的是700多个空行，中间有一些文本，我不想手动执行此操作。

I’m a programmer, so I’d rather spend 5 minutes making a task easier rather than spend the same amount of time doing an annoying job.

我是一名程序员，所以我宁愿花5分钟简化任务，也不愿花相同的时间来完成烦人的工作。

I searched a bit and found this simple way to do so: replace \n\n with \n.

我搜索了一下，发现这样做的简单方法：用\n\n替换\n\n \n 。

I ran “replace all” inside the file, and half of the lines were removed. So I ran it again, and again and again, until I got to 1 empty line.

我在文件中运行了“全部替换”，并且删除了一半的行。 因此，我一次又一次地运行它，直到到达1个空行。

Update: \n\n+ will replace all lines at once without having to repeat the operation

更新： \n\n+将一次替换所有行，而无需重复操作
