问题
I have a file from a project that uses GIT as repository. For that file I need to find out to which revision this file belongs to. The file is stand-alone outside of an repository (not tracked) therefore the standard git commands do not work.
Is there a way to determine the revision this file belongs to only based on it's filename and it's content?
回答1:
I don't think there's a one-shot command to do this - git's object model makes it quite laborious to work back from a blob to commits that might reference it. Here's one way of doing it, though. First of all, find the hash of the file that git would use, with:
git hash-object foo.c
Suppose that returns f414f31. Then you can use a script like the following:
for c in $(git rev-list --all)
do
( git ls-tree -r $c | grep f414f31 ) && echo Found the blob in commit: $c
done
... to show all the commits that contain that blob. If you want to know which branches those commits are on, you can do:
git branch -a --contains 1a2b3c4d
