To display the list of commits that are reachable from a specified commit, along with the differences between those commits and the specified commit in Git, you can use the following commands:
1. List Commits Reachable from a Specified Commit:
You can use the git log command with the --graph and --oneline options for simplicity. Replace <commit> with the actual commit hash you are interested in.
git log <commit> --oneline --graph
This will show you a visual representation of the commit history that is reachable from the specified commit.
2. Show Differences:
To see the differences between the specified commit and its reachable commits, you can use the git diff command. If you want to see the difference between a specific commit and all of its reachable commits, you can do something like this:
git diff <commit> <commit>^..HEAD
Here, <commit>^ refers to the parent of the specified commit, effectively showing the differences between the specified commit and all of its descendants (i.e., reachable commits).
If you want to see a summary of commits along with their diffs, you can put it all together using a loop or script. Here's an example using a simple bash loop:
git log --format="%H" <commit>..HEAD | while read commit_hash; do
echo "Differences with commit $commit_hash:"
git diff <commit> $commit_hash
done
Breakdown:
- git log --format="%H" retrieves the commit hashes of all commits reachable from the specified commit up to HEAD.
- The loop reads each hash and runs git diff to show the differences between the specified commit and each reachable commit.
Note:
- Replace <commit> with the specific commit hash you want to compare against.
- The output of the commands will depend on your current branch context and the state of your repository. Make sure you're in the correct repository and branch.
