git-checkout二進制文件的舊版本，而不會過度工作副本

Question

我有一個二進制文件文件（foo.bin）在我的git倉庫中。

如何在不覆蓋工作副本中的文件的情況下籤出此文件的舊版本？

喜歡的東西：

git checkout tag-name -- foo.bin > foo-tag-name.bin 

Answer 1

你的命令幾乎是正確的：

git show tag-name:foo.bin > foo-tag-name.bin 

git help show還給出了另一個例子：

git show next~10:Documentation/README 
     Shows the contents of the file Documentation/README as they were 
     current in the 10th last commit of the branch next. 

這句法中git help gitrevisions描述：

<rev>:<path>, e.g. HEAD:README, :README, master:./README 
     A suffix : followed by a path names the blob or tree at the given 
     path in the tree-ish object named by the part before the colon. 

Answer 2

git show是你要找的命令：

git show tag-name:foo.bin > foo-tag-name.bin
