How to Exclude Commits From Git?

3 minutes read

To exclude commits from Git, you can use the git rebase command. First, identify the commit you want to exclude by using git log. Once you have the commit hash, use git rebase -i HEAD~n command, where n is the number of commits you want to go back.


In the interactive rebase window, find the commit you want to exclude and change the word "pick" to "drop" next to it. Save and exit the rebase window. Git will then remove the selected commit from the commit history.


After excluding the commit, you may need to force push the changes to the remote repository by using git push origin branch-name --force. It's important to note that excluding commits can change the history of the repository and potentially cause conflicts, so be cautious when using this method.


How to show changes in a commit in Git?

To show changes in a commit in Git, you can use the following command:

1
git show <commit_hash>


Replace <commit_hash> with the hash of the commit you want to view the changes for. This command will display the metadata of the commit (commit message, author, date) as well as the changes made in that commit (added, modified, or deleted files).


How to undo a specific commit in Git?

To undo a specific commit in Git, you can use the git revert command.

  1. Find the commit hash of the specific commit you want to undo by using git log.
  2. Use the command git revert to create a new commit that undoes the changes introduced by the specified commit.
  3. Save and exit the commit message editor that opens.
  4. Push the changes to the remote repository by using git push.


Alternatively, you can use the git reset command to undo a commit, but this method is not recommended if the commit has been pushed to a remote repository and shared with others.


How to create an annotated tag in Git?

To create an annotated tag in Git, you can use the following command:

1
git tag -a <tag_name> -m "Annotation message"


Replace <tag_name> with the name of your tag and provide an annotation message in quotes using the -m flag. This message will be associated with the tag and can provide additional context or information about the tag.


After running the command, the annotated tag will be created and stored in the repository. You can view the created tag by using the git tag command.


How to remove unwanted commits from a Git history?

To remove unwanted commits from a Git history, you can use the git rebase -i command. Here's how you can do it:

  1. Identify the commit you want to remove by using git log to view the commit history.
  2. Note down the commit hash of the commit you want to remove.
  3. Open your terminal and run the following command to start an interactive rebase:
1
git rebase -i HEAD~n


Replace n with the number of commits you want to go back in the history. For example, if you want to remove the last 3 commits, you can use HEAD~3.

  1. An interactive rebase file will open in your text editor. Find the commit you want to remove in the list of commits and delete its corresponding line.
  2. Save and close the file. Git will then reapply the remaining commits on top of the new history.
  3. If there are conflicts during the rebase, resolve them and continue the rebase with git rebase --continue.
  4. Once the rebase is complete, you can force-push the changes to the remote repository with:
1
git push origin branch-name --force


Note: Be cautious when using rebase as it rewrites history, which can cause issues for collaborators working on the same repository. It's recommended to communicate with your team before making significant changes to the Git history.


How to revert a commit in Git?

To revert a commit in Git, you can use the following command:

1
git revert <commit_id>


Replace <commit_id> with the actual commit ID of the commit you want to revert. This will create a new commit that undoes the changes made in the specified commit. You can then push this new commit to your remote repository to revert the changes.
