git revert to undo a commit safely - Step-by-Step Execution

Process Flow - git revert to undo a commit safely

Identify commit to undo

↓

Run git revert <commit>

↓

Git creates a new commit

↓

New commit reverses changes

↓

Push changes to remote (optional)

This flow shows how git revert safely undoes a commit by creating a new commit that reverses the changes.

Execution Sample

Git

git revert abc1234
# Creates a new commit that undoes abc1234

This command safely undoes the changes introduced by commit abc1234 by making a new commit that reverses them.

Process Table

Step	Action	Git Response	Resulting State
1	Identify commit abc1234 to revert	Commit hash abc1234 found	Ready to revert commit
2	Run git revert abc1234	Preparing revert of abc1234	New revert commit created (pending)
3	Git opens editor for commit message	User confirms commit message	Revert commit finalized
4	Revert commit added to branch	Commit abc1234 reversed by new commit	Branch history updated with revert
5	Optional: git push	Push successful	Remote branch updated with revert commit

💡 Revert commit created and branch history safely updated without deleting original commit

Status Tracker

Variable	Start	After Step 2	After Step 4	Final
HEAD	points to commit before abc1234	still points to commit before abc1234	points to new revert commit	points to new revert commit
Branch history	includes abc1234	includes abc1234	includes abc1234 + revert commit	includes abc1234 + revert commit

Key Moments - 2 Insights

Why does git revert create a new commit instead of deleting the old one?

Git revert adds a new commit that reverses changes to keep history safe and avoid rewriting history, as shown in execution_table step 4.

What happens if you push after revert?

Pushing sends the new revert commit to the remote repository, updating it safely without removing any commits, as in execution_table step 5.

Visual Quiz - 3 Questions

Look at the execution table, what does git do at step 3?

A Deletes the original commit

B Pushes changes to remote

C Opens editor for revert commit message

D Checks out a new branch

💡 Hint

Check the 'Git Response' column at step 3 in the execution_table

At which step is the revert commit finalized?

A Step 3

B Step 1

C Step 5

D Step 2

💡 Hint

Look at the 'Resulting State' column for when the revert commit is finalized

If you skip pushing after revert, what happens to the remote branch?

A Remote branch gets revert commit automatically

B Remote branch stays unchanged

C Remote branch deletes the original commit

D Remote branch resets to previous commit

💡 Hint

Refer to step 5 in execution_table about pushing changes

Concept Snapshot

git revert <commit>
Creates a new commit that reverses the changes of the specified commit.
Does NOT delete or rewrite history.
Safe way to undo changes in shared branches.
Push the revert commit to update remote repository.

Full Transcript

Git revert safely undoes a commit by creating a new commit that reverses the changes. First, you identify the commit to undo. Then you run 'git revert <commit>'. Git prepares a new commit that reverses the changes and opens an editor for the commit message. After confirming, the revert commit is finalized and added to the branch history. Optionally, you push the new commit to update the remote repository. This method keeps the original commit intact, preserving history and avoiding conflicts.
