What is git merge and how to avoid turning it into conflict theater

Merge is about joining two lines of work into one history.

What it is

Git merge joins changes from one branch into another. It is useful when a separate task is finished and needs to return to the main line.

If the branches touched different places, merge is quiet. If they touched the same lines, a conflict appears and you have to fix it manually.

Why it matters

Merge gives you three things:

• a way to bring work back into main;
• a visible history of what got merged;
• a safe way to combine changes after review.

How to work with it

Typical flow:

git switch main
git pull

git merge feature/login-validation

git status
git push

If there is a conflict, Git shows the file and the place where you need to choose the right version. After fixing it, do not forget to check the build.

What to avoid

• do not merge a branch that has not been checked yet;
• do not ignore conflicts and leave them “for later”;
• do not merge without understanding what will enter main;
• do not confuse fast-forward with a full merge when you need a visible merge point.

Conclusion

Merge is the normal end of branch work. If you do it carefully, history stays clean and the code stays coherent.

In simple words

merge = “carefully join two branches into one history.”
