How can I easily find the most similar(or nearest) version(or commits) a source code tree is based from the open source git repo?

Question

My conditions are:

I have a source codes tar ball file, e.g. binutils-gdb.tar.gz
I know that it's from git://sourceware.org/git/binutils-gdb.git
But I've no ".git" directory in binutils-gdb.tar.gz, it means I don't know which version or commit the binutils-gdb.tar.gz is from

My question: How can I know which version or commit in git://sourceware.org/git/binutils-gdb.git generating my current binutils-gdb.tar.gz?

I know that if I check the files in binutils-gdb.tar.gz one by one, e.g. the version file, it's possible I could get the correct version or commits for the binutils.tar.gz in git://sourceware.org/git/binutils-gdb.git But this kind of manual checking work is too tedious, do we have some tools/scripts to do this work?

Thanks in advance!!!

You can:

extract the all the files in tar.gz
clone git repo
compare both trees
if all files are equal HEAD is the commit in the tar.gz
else checkout HEAD~1
go to compare

Thanks for your reply. If HEAD~1 is not same as my source tree, then HEAD~2? Then HEAD~3? This is too tedious, any other more powerfull tools or solution to this ? – Clock ZHONG Mar 07 '22 at 08:36
You can easily create a script to do it – Diego Torres Milano Mar 07 '22 at 15:59
