bash/zsh function for pushing a new git branch to remote

git-push-new-branch.sh

# Get the current git branch name
git-branch-name() {
    git symbolic-ref --short HEAD
}

# Push new branch to origin and set up tracking
git-push-new-branch() {
    git push -u origin $(git-branch-name)
}

Typical use:

source git-push-new-branch.sh     # or add it to your .bashrc

git checkout master
git checkout -b my-new-branch
# ... make changes ...
git commit -am "I created a new branch with some changes"
git-push-new-branch   # pushes to origin/my-new-branch and local branch will track it
