您知道该文件属于哪个提交（即：特定修订版）？然后执行：

  git checkout< commit> &LT;文件> 
 

其他命令：

  git checkout HEAD〜N< file>

How can I check out a particular version of one file in git?

I found this mail on the mailing list, which said:

$ git checkout HEAD~43 Makefile
$ git reset Makefile

But I don't understand how to find out 'HEAD~43', if I do a git log aFile, how can I find out which 'HEAD~43' I should use?

And why do I need to run git reset for that file? What does it do?

You know what commit (ie: the specific revision) the file belongs to? Then do:

git checkout <commit> <file>

The other command:

git checkout HEAD~N <file>

Is for when you want to get a version of the file from a range back (which I do for nostalgia).
