Git log -L going forward

Question

I\'m trying to understand if it is possible to determine how a particular line changes \"in the future\" using git log, i.e., going to an old commit using git

Answer 1

First, find out how many tracked development directions (branches) there have been since the specific commit:

git branch -a --contains b5a3d3f2701bab98318a92eaf781653392494b43

It lists all the branches that contain this commit. For example, there might be origin/foo and origin/bar. These branches are the latest (at the moment the repository is cloned) revision of each direction. Then run

git log -L 37,37:README.md b5a3d3f2701bab98318a92eaf781653392494b43..origin/foo

to see how Line 37 of README.md has been changed since the specific commit till the latest revision of foo.
