Add a GitHub and GitLab repo as remote origins so that when you push, the changes are pushed to both repositiories. Useful for keeping a mirror of all your GitHub repos on GitLab. Does this for every directory in the present working directory.

github-gitlab-remote.sh

for dir in */; do
    repo=${dir%/*}
    user="foo"
    cd $dir
    git remote remove origin
    git remote add github git@github.com:$user/$repo.git
    git remote add gitlab git@gitlab.com:$user/$repo.git
    git remote add origin git@github.com:$user/$repo.git
    git remote set-url --add --push origin git@github.com:$user/$repo.git
    git remote set-url --add --push origin git@gitlab.com:$user/$repo.git
    git pull origin master
    git push --set-upstream origin master
    cd ..
done
