Please check below example of branching in the real world.

1. Start implementation on a User management feature.
2. Create a branch for example feat/ECS-12-user-management.
3. Commit your work in feat/ECS-12-user-management branch.

At this point, you identify one bug in production

1. Switch to master branch.
2. Create a branch hotfix/user-profile-not-working.
3. After code review, merge hotfix/user-profile-not-working branch into master and push.
4. Switch to feat/ECS-12-user-management branch and continue your work.

List all local branches in repository

$ git branch

a * will appear next to the currently active branch. With -a: show all branches (with remote).

$ git branch [-a]

$ git branch <branch-name>

Switch working directory to the specified branch. With -b.
Git will create the specified branch if it does not exist.

$ git checkout [-b] <branch-name>

Switch branch
switch to another branch and check it out into your working directory

$ git checkout <branch-name>

Sometimes branches need to be cleaned up for book keeping or organisational purposes. The fully delete a branch, it must be deleted locally and also remotely.

$ git branch -D <branch-name>
$ git push <remote> <branch-name>
