在 vim 中就地编辑文件 [英] Edit a file in-place in vim

问题描述

通常，您实际上不会在 vim 中编辑文件.如果你运行 vim foo，编辑、写入并退出，vim 会取消链接 foo 并创建一个新文件和一个名为 foo 的新链接.但是，如果文件有多个链接，那么 vim 实际上会修改文件.例如:

Normally, you don't actually edit a file in vim. If you run vim foo, edit, write and quit, vim unlinks foo and creates a new file and a new link named foo. But, if the file has more than one link, then vim actually modifies the file. For example:

$ ls -i foo
19428852 foo
$ vi foo
$ ls -i foo
19428857 foo
$ ln foo bar
$ vi bar
$ ls -i bar
19428857 bar

我一直在寻找一种实际编辑文件的方法，似乎有两种选择.使用 ed，或使用 vim 但确保在我编辑之前至少有两个指向该文件的链接.我想这个问题是学术性的，因为如果只有一个链接，vim 创建一个新文件并不重要，如果在编辑过程中创建链接，vim 似乎会做正确的事情，但我很好奇:

I've been looking around for a way to actually edit a file, and it seems there are two choices. Use ed, or use vim but ensure that there are at least two links to the file before I edit. I suppose the question is academic, as it doesn't really matter that vim creates a new file if there is only one link, and vim seems to do the right thing if links are created while the editing is underway, but I'm curious:

是否可以让 vim 始终编辑文件而不创建新文件?

is it possible to make vim always edit the file, and not create a new one?
