Configuration

User setup

git config user.name "Name"
git config user.email '<[email protected]>'

Tip: Add --global flag for global config.

Sign commits using a GPG key

List your gpg keys:

gpg --list-secret-keys --keyid-format LONG
/Users/username/.gnupg/secring.gpg
  ------------------------------------
sec   4096R/2AA5B24170567CE0 2019-01-01 [expires: 2020-01-01]

Tip: For a GPG key setup check out Generating a new GPG key

Add your GPG signing key in Git globally:

git config --global user.signingkey 2AA5B24170567CE0

Tip: For disable signing commits temporarily try: git config --global commit.gpgsign false

Global .gitignore file

git config --global core.excludesfile ~/.gitignore

Add remote origin

git remote add <remote_origin> <repo_url>

Remove remote origin

git remote remove <remote_origin>

Commiting

Show the working tree status

git status

Tip: Use -sb flag to see the status in a compact way.

Stage files to commit

git add <some_files_or_directories>

Tips: Use a dot git add . to stage all files for commit.

Commit a change

git commit <some_files_or_directories>

Tips: Add -m "Message here" to commit with a message directly.

Change last commit message

git commit --amend

Tip: Add --author="Name <name@email>" to override author.

Revert previous commit but keeping last changes

git reset HEAD^

Revert previous commit (no safety)

Caution: This command throws away all your uncommitted changes. For safety, you should always check that the output of git status is clean (that is, empty) before using it. See this thread for more details.

git reset --hard HEAD

Cherry-pick a commit

Cherry pick means to choose a commit from one branch and apply it onto another. See this thread for more details.

git cherry-pick <other_branch_parent_commit> -m 1

Note: Parent number starting from 1. See this thread for more details.

Cherry-pick last commit

git cherry-pick $(git rev-parse <other_branch_name>) -m 1

Branching

Create a new branch and start it

git checkout -b <new_branch>

Checkout a remote branch

git checkout -tb <local_branch> origin/<remote_branch>

Rename a branch

git branch -m <new_branch_name>

Tip: Use -M flag to forcing instead.

List all branches

git branch -a

List remote branches

git branch -r

Delete branches

git branch -d <branch_name_1> <branch_name_2> <branch_name_n>

Tip: Tip: Use -D flag to forcing instead.

Merge two branches

git checkout <target_branch>
git merge <source_branch>

Tip: Add --squash flat for a squash merging.

Pulling

Pull changes from remote server but saving uncommitted changes

This command makes this for you:

• Save your uncommitted changes locally with git stash.
• Local changes you made will be rebased on top of the remote changes.
• Return your uncommitted changes locally again.

git pull <remote_origin> <target_branch> --rebase --autostash

Tip: Skip --rebase if you want to merge your changes with the remote changes.

Pushing

Push changes to remote server

git push <remote_origin> <branch_name>

Logging

Show log info of last commit

git log -1 HEAD

Show logs in a fancy way

git log --color --graph --pretty=format:'%Cred%h%Creset -%C(yellow)%d%Creset %s %Cgreen(%cr) %C(bold blue)<%an>%Creset' --abbrev-commit

Tagging

Create a tag

git tag v1.0.0

Delete a tag

git tag -d v1.0.0

Reflog

Find and manage the history of all your Git stuff

git reflog

Resolve conflicts

TODO

Aliases

If you don't want to type the entire text of each of the Git commands above, you can easily set up an alias for each command and then just run it.

Example: We will create an alias last that shows log info of the last commit.

git config --global alias.last 'log -1 HEAD'

Then just run:

git last
