Understanding Git Merge

A Git merge combines changes from different branches. However, sometimes a merge may introduce conflicts or unwanted changes. Knowing how to undo a merge allows developers to revert to a previous state without losing important work. This guide will explore the common scenarios and commands involved in undoing a Git merge.

Why Undo a Git Merge?

• Using Git Reset: This command allows you to reset your branch to a previous commit, effectively undoing the merge.
• Using Git Checkout: This method involves checking out a specific commit before the merge.
• Using Git Revert: This command creates a new commit that undoes the changes made by the merge.

Best Practices for Version Control

Maintaining a structured approach to version control can prevent the need for frequent undos. Regular commits, clear branching strategies, and effective communication within teams are essential.
