在 Vim 中，什么是“备用文件"? [英] In Vim, what is the "alternate file"?

问题描述

我刚刚在 Vim 中运行了 :help registers 并注意到 # '包含备用文件的名称'.

I just ran :help registers in Vim and noticed that # 'contains the name of the alternate file'.

我看过一个重命名文件的例子，如下所示:

I have seen an example for renaming files that goes like this:

" Save the current file, foo.txt, as bar.txt
:w bar.txt
" Start editing bar.txt
:e#

显然在这种情况下，您刚刚保存的文件是备用文件".

So apparently in that case, the file you just saved out is the "alternate file."

有人能给我一个更一般的替代文件"的定义吗?你还能用它做什么?

Can someone give me a more general definition for the "alternate file" and what else you might use it for?

推荐答案

备用文件是在当前窗口中最后编辑的文件.实际上，当您使用某些命令打开一个新缓冲区时，如果显示的缓冲区具有与之关联的文件名，则该文件名将被记录为备用文件名.

The alternate file is the file that was last edited in the current window. Actually when you use some command to open a new buffer, if the buffer that was displayed had a filename associated with it, that filename is recorded as alternate file name.
