git branch -d <branch name> Delete a specific branch


git push origin <branch name> Push a branch to a remote repository


git merge <branch name> Merge branch into master branch (ensure that you're inside the master branch)

Stashing

Merge Conflicts


When you encounter a merge conflict, first... don't freak out. This just means you're being given the ability to choose which code you want to choose to go with.

Sample Conflict


You run git pull on a repo that has changes that conflict with your local copy.
You're presented with the following error message:

error: The following untracked working tree files would be overwritten by merge:
README.md
Please move or remove them before you merge.
Aborting

Natural Response


How to Fix a Merge Conflict


It's actually not that hard to fix merge conflicts, simply run git status and it will show you where the conflict exists. An example conflict might look like this:

<<<<<<< HEAD
# Git Homepage
=======
# git-guide

> A guide for working with git
>>>>>>> a1dfac148fb86311a453a9de338e4d7b9389ade5
The <<<<<<< HEAD, =======, and >>>>>>> symbols are simply showing you where the conflict is. You have the choice to pick what you want to keep, what you want to remove, etc. After picking out the implementation that you want you can run:

git add .
git commit -m 'some commit message'
git push

And you will be good to go.
Cloning


git clone <link to repo> Clone a repository from a remote source, such as GitHub

Rebase


git rebase master While working on a branch you can bring in committed changes from another branch. This is helpful for ensuring that your feature branch can be cleanly merged with the master branch
