To rollback from the last commit in Git, you can use the "git reset" command. This command allows you to move the HEAD pointer to a previous commit, effectively undoing the last commit. You can use the "git reset --soft HEAD~1" command to rollback to the previous commit while keeping the changes staged. Or you can use the "git reset --hard HEAD~1" command to rollback to the previous commit and discard any changes made in the last commit. It's important to be careful when using the "git reset --hard" command as it can result in the loss of any changes made in the last commit.

How to rollback to a specific commit without affecting other changes in Git?
To rollback to a specific commit in Git without affecting other changes, you can use the following command:
1
|
git checkout <commit_hash>
|
Replace <commit_hash> with the hash of the commit you want to rollback to. This command will put your project in the state it was at that specific commit, without losing any of the changes you made after that commit.
If you want to create a new branch to work on the rolled back code:
1
|
git checkout -b new_branch_name <commit_hash>
|
This will create a new branch with the code at the specified commit, allowing you to make changes without affecting the main branch.
How to revert to the previous state before the last commit in Git?
To revert to the state before the last commit in Git, you can use the "git reset" command.
Here are the steps to revert to the previous state before the last commit:
- Open your terminal or command prompt.
- Navigate to the Git repository where you want to revert the changes.
- Type the following command to revert to the commit before the last one:
1
|
git reset --hard HEAD~1
|
This command will reset your working directory and staging area to the state of the commit before the last one. The "--hard" option will discard all changes in your working directory and staging area.
- If you want to keep the changes in your working directory, you can use the following command instead:
1
|
git reset HEAD~1
|
This command will only reset the staging area to the state of the commit before the last one, leaving your working directory unchanged.
- Finally, you can use the "git log" command to verify that you have successfully reverted to the previous state before the last commit.
Note: Be careful when using the "git reset" command as it can discard changes permanently. Make sure to backup any important changes before reverting to a previous state.
What is the process for rolling back a merge commit in Git?
To roll back a merge commit in Git, you can use the git revert command to create a new commit that undoes the changes introduced by the merge commit. Here is the process for rolling back a merge commit:
- Find the hash of the merge commit that you want to roll back by using the git log command.
- Use the git revert command followed by the hash of the merge commit to create a new commit that undoes the changes introduced by the merge commit. For example, git revert .
- Edit the commit message if needed and save the changes.
- Push the revert commit to the remote repository by using the git push command. For example, git push origin master.
After following these steps, the merge commit will be rolled back, and the changes introduced by the merge will be undone in the codebase.
