How to pull a specific file with GIT?
提问by Paul Casal
Say you just want to get rid of the changes you've made to one file, and get back to whatever is in the repository. I used to do this in svn:
假设您只想删除对一个文件所做的更改，并返回到存储库中的任何内容。我曾经在 svn 中这样做：
rm a-file.txt
svn update a-file.txt
What is the equivalent in Git? I know how to fetch/pull evrythingfrom the repository, but how about one single file?
Git 中的等价物是什么？我知道如何获取/拉evrything从仓库中，但如何对一个单一的文件？

To undo your (uncommitted) changes:
要撤消您的（未提交的）更改：
git checkout a-file.txt
If you have committed changes and want to undo them back to a certain previous commit:
如果您已提交更改并希望将它们撤消回某个先前的提交：
git checkout [some-older-commit-ref] a-file.txt
Btw, with Subversion you should have done:
顺便说一句，使用 Subversion 你应该这样做：
svn revert a-file.txt
