Cheat Sheet

Useful git commands

Branch

Move changes to another branch

git stash

# To create a new branch
git checkout -b correct-branch

# To use an existing branch...
# git checkout correct-branch

git stash pop

Discard local changes

git reset --hard origin/master
git pull origin master

Update parent branch

git checkout feature_abc
git checkout -b feature_def
# --> Someone changed something in feature_abc
git pull origin feature_abc

Clone

Git clone private repo

git clone https://myemail%40gmail.com:[email protected]/my-group/my-repo.git

Where:

• myemail%40gmail.com means [email protected] and it is your username;

• 123456 is your password;

Fork

Keeping a fork up to date

Clone your fork

git clone [email protected]:YOUR-USERNAME/YOUR-FORKED-REPO.git

Add remote from original repository in your forked repository.

cd into/cloned/fork-repo
git remote add upstream git://github.com/ORIGINAL-DEV-USERNAME/REPO-YOU-FORKED-FROM.git
git fetch upstream

Updating your fork from original repo to keep up with their changes.

git pull upstream master

Manage credentials

Store credentials permanently

git config credential.helper store

Store credentials on cache

To avoid providing the same credentials every time, you may enable the Git credentials cache through the following command:

git config --global credential.helper cache

The default cache expiry timeout is 900 seconds (15 minutes) and can be changed with the --timeoutoption as follows:

git config --global credential.helper 'cache --timeout=300'

If you want the daemon to exit early, forgetting all cached credentials before their timeout, you can issue an exit action:

git credential-cache exit

Module

Remove submodule

mv a/submodule a/submodule_tmp
git submodule deinit -f -- a/submodule    
rm -rf .git/modules/a/submodule
git rm -f a/submodule

# or, if you want to leave it in your working tree and have done step 0
# git rm --cached a/submodule
mv a/submodule_tmp a/submodule
