如何在vim中复制以数字开头的所有行？

Question

我有一个包含标题和代码的文档。每个代码都有自己的行，现在我需要复制其中的所有代码，每个代码都放在单独的行中。它们都以数字开头，Vim可以轻松实现。

该文档如下所示：

TITLE
123-456-4252-2

Other TITLE 2
123-456-4252-X

A nice TITLE 3
523-456-4252-2

...

Answer 1

You can use the :global command!

qaq:g/^\d/y A

After this, the lines are in the a register. Afterwards you can paste the copied lines with "ap.

Explanation:

• qaq records a macro in a and immediately ends it, effectively clearing it.
• :g/foo/bar executes the bar command for every line that matches foo.
• ^\d is a regex that matches lines starting with a number.
• y A yanks into the a register, but in append-mode.
