Git: Reference Sheet

Git is the most universally adopted version control software and is often used alongside remote repositories like GitHub and GitLab for developing, managing and distributing code.

Full Git documentation can be found here, or using man git.


Getting Started

You can create a repository with either of the following commands.

clone git clone Copies a remote repository into your current directory.
init git init Creates a new empty repo in your current directory.


add git add <file1> <file2> Adds <file1> and <file2> to the staging area.
git add *.py  Adds all python files in the current directory to the staging area.
status git status Lists changes in working directory, and staged files.
commit  git commit Records everything in the staging area to your repository. The default text editor will prompt you for a commit message.
git commit -m "Commit message" Records everything in the staging area to your repository with the commit message "Commit message"
git commit --amend Modify last commit instead of creating a new one. Useful for fixing small mistakes.
log  git log Prints commit history of repo.
git log <filename> Prints commit history of <filename>.
reset  git reset Removes all files from staging area. (Opposite of git add)
git reset <filename> Removes <filename> from staging area.


By default, fetch, pull and push will operate on the origin repo. This will be the repo you cloned from, or set manually using  git branch --set-upstream-to <origin>.


Running the command git config --global credential.helper store will store your login details next time they are entered, saving you from having to enter them again.

fetch  git fetch Gets status of 'origin'. git fetch does not change your working directory or local repository (see git pull). 
git fetch <repo> <branch> Get status of <repo> <branch>.
pull  git pull Incorporates changes from 'origin' into local repo. 
git pull <repo> <branch> Incorporates changes from <repo> <branch> into local repo.
push  git push Incorporates changes from local repo into 'origin'. 
git push <repo> <branch> Incorporates changes from local repo into <repo> <branch>


If you are working without collaborators, there should be no reason to have a conflict between your local and your remote repo. Make sure you always git pull when starting work on your local and git push when finished, this will save you wasting time resolving unnecessary merges.


At an introductory level, it is best to avoid workflows that lead to multiple branches, or requires merging.

branch  git branch List branches.
git branch <branch-name> Create new branch <branch-name
checkout git checkout <branch-name> Switch to editing branch <branch-name>
merge git merge <branch-name> Merge <branch-name> into current branch.
