git-find-worktree

A basic tool to identify the original git commit corresponding to a working tree where the .git has been lost.

Unfortunately in the industry, poor practicies may lead to an original git repository losing it's history contained in the .git directory. On top of this, some modifications may be applied without keeping trace of the history. Eventually, the git history will have to be recovered, wether to get updates from upstream, or to publish the local modifications. For this, it is necessary to find which commit the local working tree originated from.

This tool aims to do just that. For each commit on a given branch from the original repository, it will compare the local working tree and report the commit ID with the least differences.

This was inspired by the following stack overflow question : git find commit from "working tree"

Dependencies

The following packages are required:

• bash
• git
• awk

How to use it

1. Clone the original repository corresponding to the working tree.

$ git clone $ cd

2. Erase all contents except the .git and overwrite with your working tree.

$ rm -rf * $ cp -r /* . $ git add -a

3. Run the script with the name of the branch you want to examine.

$ /git-find-worktree.sh master

You will get results like this:
