Let's say I have a Git repo with branch A and branch B.
Branch B is currently checked out (i.e. .git/HEAD contains refs/heads/B).
Now, without checking out branch A, how to view the history (log) of path/file in branch A?

Following git help rev-parse, I've attempted to use git log A:path/file, but that doesn't seem to work (outputs nothing). Why?

Try this (without the angle brackets):

git log <branch> -- <path/to/file>
