Git Commands

Getting & Creating Projects

Command	Description
git init	Initialize a local Git repository
git clone ssh://git@github.com/[username]/[repository-name].git	Create a local copy of a remote repository

Basic Snapshotting

Command	Description
git status	Check status
git add [file-name.txt]	Add a file to the staging area
git add -A	Add all new and changed files to the staging area
git commit -m "[commit message]"	Commit changes
git rm -r [file-name.txt]	Remove a file (or folder)
git reset head --hard	Resets local repo to last commit/head - will lose all the changes
git reset --soft HEAD~	Resets local repo's current (n) commit to n-1 commit - without losing the nth committed changes
git stash	To store current changes without commiting
git pop	To bring back the stashed changes
git clean -df	To delete unwanted untracked files
git checkout -	To move to previous branch after checking out new branch

Branching & Merging

Command	Description
git branch	List branches (the asterisk denotes the current branch)
git clone --branch 11.5 --shallow-since=3m https://github.com/MariaDB/server.git mariadb-serverh	This will make a clone that only tracks branch 11.5 and no other branches. Additionally this uses the shallow clone feature to fetch commit history only for the past 3 months instead of the entire history (which in this example otherwise would be 20+ years).
git branch -a	List all branches (local and remote)
git branch [branch name]	Create a new branch
git branch -d [branch name]	Delete a branch
git push origin --delete [branch name]	Delete a remote branch
git checkout -b [branch name]	Create a new branch and switch to it
git checkout -b [branch name] origin/[branch name]	Clone a remote branch and switch to it
git branch -m [old branch name] [new branch name]	Rename a local branch
git checkout [branch name]	Switch to a branch
git checkout -	Switch to the branch last checked out
git checkout -- [file-name.txt]	Discard changes to a file
git merge [branch name]	Merge a branch into the active branch
git merge [source branch] [target branch]	Merge a branch into a target branch
git stash	Stash changes in a dirty working directory
git stash clear	Remove all stashed entries
git reset --hard origin/master	To override local git with that of the remote. This will reset everything to match the remote

Sharing & Updating Projects
