What is difference between Merge and rebase?

Git rebase and merge both integrate changes from one branch into another. Where they differ is how it’s done. Git rebase moves a feature branch into a master. Git merge adds a new commit, preserving the history.

How can you temporarily switch to a different commit?

First, use git log to see the log, pick the commit you want, note down the sha1 hash that is used to identify the commit. Next, run git checkout hash .

What is a git merge commit?

Git merging combines sequences of commits into one unified history of commits. There are two main ways Git will merge: Fast Forward and Three way. Git can automatically merge commits unless there are changes that conflict in both commit sequences.

Is it better to rebase or merge?

If you want to see the history completely same as it happened, you should use merge. Merge preserves history whereas rebase rewrites it . Rebasing is better to streamline a complex history, you are able to change the commit history by interactive rebase.

Why rebase is used in git?

Git Rebase Rebase is another way to integrate changes from one branch to another. Rebase compresses all the changes into a single “patch.” Then it integrates the patch onto the target branch. Unlike merging, rebasing flattens the history because it transfers the completed work from one branch to another.

What is the difference between a mother and a parent?

How do you reattach a detached head?

What is a parent branch?

How do you pull changes from the parent branch?

Assuming your call to create B was git clone /path/to/server/A , you just have to do a git pull and you’re done. That’s how git pull works: first it fetches the changes from the upstream (the tracked branch A in your case), then it merges these changes into the branch that tracks the tracked branch ( B in your case).
