I'm trying to find a way to get to state where i can do

$ git log <path>

Or any other variants of it without introducing any non-default scripts/features/keywords and limiting keywords to one to avoid any related problem...

One of my friends said that git is not working for their development model... C++ development with static linking across the board, where they need to see exactly which version of the file has got to the executable. Roughly, they are using CVS' keywords and revision numbers and a script wich matches them between two versions of the executables.

I've got curious if Git can support it and how it can be done with minimal changes to workflow.

Actually, grep "SHA-1 A" will show added path(s) only, so this is resolved

How is that? It seams to me that git log <path> will show only commits where <path> was changed/committed? Considering the fact that I've got the initial path from the blob, i should get the exact commit history (or last commit in my example) for the file(s) (Files if renaming occurred without content change).

Thanks, Eugene
