GIT - HowTo's about "branches"

How to list commits from a specific branch only ?

How to move commits to another branch ?

This typically happens when you've committed on master, then realized that those commits better suit a feature branch. In other words, how may I go from this :

	A---B---C---D---E master

to this :
	      C---D---E newBranch
	     /
	A---B master

Before going further, make sure you have no uncommitted changes left.

Method 1 : (source) :

  1. switch to a new branch :
    git checkout -b newBranch
  2. make master point to some older commit :
    git branch -f master HEAD~3
    3 is the number of commits to move from master to newBranch

Method 2 (source) :

git branch newBranch      # Create a new branch, saving the desired commits
git reset --hard HEAD~3   # Move master back by 3 commits (GONE from master)
git checkout newBranch    # Go to the new branch that still has the desired commits


NB : instead of resetting to a nb of commits, you can reset until a specific commit ID :
git reset --hard a1b2c3d4
How it works (source) :
You want to go back to C, and move D and E to the new branch. Here's what it looks like at first:

A-B-C-D-E (HEAD)
        ↑
      master

After git branch newBranch:

    newBranch
        ↓
A-B-C-D-E (HEAD)
        ↑
      master

After git reset --hard HEAD~2:

    newBranch
        ↓
A-B-C-D-E (HEAD)
    ↑
  master

Since a branch is just a pointer, master pointed to the last commit. When you made newBranch, you simply made a new pointer to the last commit. Then using git reset you moved the master pointer back two commits. But since you didn't move newBranch, it still points to the commit it originally did.

Method 3 : cherry-picking (source) :

NB : if you checkout newBranch from the existing master branch it ALREADY has those three commits included in it, so there's no use in picking them. At the end of the day to get what the OP wanted, you'll still have to do some form of reset --hard HEAD.

Step 1 - Note which commits from master you want on a new branch :

git checkout master
git log

Note the hashes of (say 3) commits you want on newBranch. Here I shall use:
C commit: 9aa1233
D commit: 453ac3d
E commit: 612ecb3

    Note: You can use the first seven characters or the whole commit hash

Step 2 - Put them on the new branch

git checkout newBranch
git cherry-pick 612ecb3
git cherry-pick 453ac3d
git cherry-pick 9aa1233

NB : the order is important. You want to do the oldest commits first
