Add gitpullall() function to ~/.bashrc (or ~/.bash_aliases) for bash and ~/.zshrc for zsh.

e.g.) add the information of gihub, gitlab and bitbucket remote repositories to your local git repository.

git remote add github git@github.com:YOUR_USERNAME/YOUR_PROJECT.git
git remote add gitlab git@gitlab.com:YOUR_USERNAME/YOUR_PROJECT.git
git remote add bitbucket git@bitbucket.org:YOUR_USERNAME/your_project.git

then run

gitpullall
