Update a single file from git
提问by Arjan
I would like to update a specific file in a repository that I use.
我想更新我使用的存储库中的特定文件。
Basically I have repo X, which has N files.
基本上我有 repo X，它有 N 个文件。
For one test, I need to have the latest and greatest of a specific file, since my application is already loaded, I can't just download the whole project again.
对于一项测试，我需要拥有最新和最大的特定文件，因为我的应用程序已经加载，我不能再次下载整个项目。
Is there a way to tell git to get from the repo, the latest and greatest version of just a specific file, without sync the whole repo/project?
有没有办法告诉 git 从 repo 中获取，只是一个特定文件的最新和最好的版本，而不同步整个 repo/项目？
I see that many uses the archive option of git, which to me seems a bit an overkill...I need to send a command to archive, and then another to unarchive on my local directory; while I would like that git would simply look at the repo, and if there are changes only to that specific file, it will update it.
我看到很多人使用 git 的存档选项，对我来说这似乎有点矫枉过正……我需要发送一个命令来存档，然后再发送一个命令在我的本地目录中取消存档；虽然我希望 git 只查看 repo，如果仅对该特定文件进行了更改，它将更新它。
How do you do that? I can't see in Git manual a way to specify a file in the repo. I use regular git from console, no UI nor Github.
你是怎样做的？我在 Git 手册中看不到在 repo 中指定文件的方法。我从控制台使用常规 git，没有 UI 或 Github。

First make sure you have the latest and greatest version available in your local git repo:
首先确保您的本地 git 存储库中有最新和最好的版本：
git fetch origin
Then retrieve the one specific file you're looking for
然后检索您要查找的特定文件
git checkout origin/master -- path/to/the/file
The --tells gitthat all other arguments are files, not parameters.
该--通知git所有其他参数是文件，没有参数。
