To show the changes introduced by a commit in a format that resembles a patch, you can use the git show command with the --patch option (or simply -p). Here's how you can do that:
1. Identify the Commit Hash: First, you need the hash of the commit you want to see changes for. You can find this by running git log to display the commit history.
2. Use git show: Once you have the commit hash, you can run the following command:
git show <commit-hash> --patch
Replace <commit-hash> with the actual hash of the commit.
3. Example: If your commit hash is abc1234, you would run:
git show abc1234 --patch
4. Output: This will display the commit message, author information, and the changes made in that commit in a diff format, showing which lines were added (prefixed with +) and which were removed (prefixed with -).
Alternative Using git diff
If you want to see the differences between two specific commits, you can use the git diff command:
git diff <commit-hash1> <commit-hash2> --patch
This way, you can compare two commits and see the patch differences between them.
Note
You can also format the output further or save it to a file by redirecting the output:
git show <commit-hash> --patch > changes.patch
This would create a file named changes.patch containing the changes.
