To show the difference introduced by each commit since a branch was created, you can use a combination of Git commands to inspect the commit history and view the differences. Here’s a step-by-step guide on how to do that:
1. Identify the Base Commit/Branch: First, determine the commit or branch you want to compare against. This is usually the point where your feature branch diverged from the main branch (e.g., main or master).
2. Use git log: Run the git log command to list all the commits since the branch was created. You can find the commit hash of the base commit (the tip of the branch you are branching from).
git log --oneline --graph --decorate YOUR_BRANCH_NAME
3. Comparing Commits: Once you know the commit hashes, you can use git diff to see the changes introduced by each specific commit. To view the differences introduced by each commit, you can also loop through each commit. Here’s one way to do it manually:
git log --oneline BASE_BRANCH..YOUR_BRANCH_NAME
This command gives you a list of all commits from your branch that aren’t in the base branch.
4. Show Differences per Commit: For each commit, you can use the following command:
git diff COMMIT_HASH^! # Replace COMMIT_HASH with the actual commit hash
This will show you the changes introduced by that specific commit.
5. Automate the Process: If you want to automate this process to get the differences for all commits in one go, you can use a loop in your shell script (this is assuming a Unix-like shell):
for commit in $(git rev-list BASE_BRANCH..YOUR_BRANCH_NAME); do
echo "Changes introduced by commit: $commit"
git show $commit
done
Replace BASE_BRANCH and YOUR_BRANCH_NAME with the appropriate branch names.
6. Viewing Interactive Difference: If you want an interactive way to see the changes, you can also use:
git difftool BASE_BRANCH..YOUR_BRANCH_NAME
This uses your configured difftool to show the changes between the two branches.
