Git Cheat Sheet

Its hard to memorize all the important Git commands by heart, so I thought it’s better to keep a personal Git cheat sheet for myself. So I don’t want to Google it every time whenever I need to check some syntax. So here it is.

Git Basics

• Initialize an empty Git repository
  git init

• Create a local copy of a remote repository
  git clone <repo>

• Check status of the files are stages, unstaged, and untracked.
  git status

• Add a file to the staging area.
  git add [file-name.txt]

• Add all new and changed files to the staging area.
  git add -a

• Commit changes.
  git commit -m "[commit message]"

• Remove a file (or folder).
  git rm -r [file-name.txt]

Undoing Changes

• Create new commit that undoes all of the changes made in , then apply it to the current branch.
  git revert <commit>

• Remove from the staging area, but leave the working directory unchanged.
  git reset <file>

• Remove a file (or folder)
  git rm -r [file-name.txt]

Git Config

To set your global username/email configuration:

• Set your username:
  git config --global user.name "FIRST_NAME LAST_NAME"

• Set your email address:
  git config --global user.email "MY_NAME@example.com"

To set repository-specific username/email configuration:

• Set your username:
  git config user.name "first_name last_name"

• Set your email address:
  git config user.email "my_name@example.com"

Verify your configuration by displaying your configuration file: cat .git/config

Sharing & Updating Projects

• git push origin [branch name]
  Push a branch to your remote repository

• git push -u origin [branch name]
  Push changes to remote repository (and remember the branch)

• git push
  Push changes to remote repository (remembered branch)

• git push origin --delete [branch name]
  Delete a remote branch

• git pull
  Update local repository to the newest commit

• git pull origin [branch name]
  Pull changes from remote repository

• git remote add origin ssh://git@github.com/[username]/[repository-name].git
  Add a remote repository

• git remote set-url origin ssh://git@github.com/[username]/[repository-name].git
  Set a repository’s origin branch to SSH

Branching & Merging

• git branch
  List branches (the asterisk denotes the current branch)

• 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 checkout [branchYouWantToReceiveBranch]
git merge [branchYouWantToMergeIntoBranch]
  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

Inspection & Comparison

• git log
  View changes

• git log --summary
