Using git version 2

1. Linking your local repository (the one on your computer) to remote repositories on GitHub

• If you clone a repository, the command automatically adds that remote repository under the name origin.

2. The git commands fetch, pull, merge, push and sync

• The command git fetch origin fetches any new work that has been pushed to that server since you cloned (or last fetched from) it.

• The git fetch command only downloads the data to your local repository.

• If I want get changes from the remote repository called origin into my local repository I type git fetch origin.

• It doesn’t automatically merge it with any of your work or modify what you’re currently working on. You have to merge it manually into your work when you’re ready.

• the git pull command is a git fetch command followed by a git merge command.

• Git sync does everything in one command meaning pull and push read here

2. Branching

• To view the branches in a Git repository, run the command git branch

• To see both local and remote branches use git branch -a or git branch --all

• To see details of each brach use git branch -v or git brach --verbose

• git checkout -b BRANCH_NAME creates a new branch and checks out the new branch

• git branch BRANCH_NAME creates a new branch but leaves you on the same branch.

• In other words git checkout -b BRANCH_NAME does the following for you:

  git branch BRANCH_NAME # create a new branch git switch BRANCH_NAME # then switch to the new branch
