Greplace 的语法
我想使用 VIM 更改几个文件中的一些单词。为此，我发现了 Greplace，它似乎是就是这样做。但是，在 文档 中没有示例Greplace 的语法（有 Gsearch 的示例，但我需要替换功能）。
假设我想在所有“.asp”文件中将“foo”更改为“bar”，如何使用 Greplace （或任何其他方法）来实现这一点。我不关心确认（需要确认也可以，不需要确认也可以）。
I want to change some words in several files using VIM. To do this, I found out about Greplace, which appears to be made to do just that. However, in the documentation there is no sample of the syntax of Greplace (there is a sample of Gsearch, but I need the replace function).
Say I want to change "foo" for "bar" in all ".asp" files, how could that be achieved with Greplace (or any other method). I do not care about confirmation (it's fine if it requires confirmation; it's also fine if it does not).

如果没有专门的插件，这件事就很简单了。
:bufdo在所有缓冲区上运行以下命令。%s/foo/bar/ge将所有行以及每行中所有出现的 foo 替换为 bar。e标志确保:s在找不到 foo 时不会发出错误，因为 foo 可能并不存在于所有文件中。|是 Vim 分隔多个命令运行的方式。请参阅:help :barupdate仅当实际进行了任何更改时才会将文件保存回磁盘。It's trivial to do without a dedicated plugin.
:bufdoruns the following commands on all buffers.%s/foo/bar/gereplaces foo with bar on all lines and all occurrences in each line. Theeflag makes sure:sdoesn't emit an error if it doesn't find foo, since foo may not exist in all the files.|is Vim's way of separating multiple commands to run. See:help :barupdatesaves the file back to disk, only if any changes were actually made.
