git push to 2 remotes code example

Example: git push to all remotes

#To push all branches to all remotes:
git remote | xargs -L1 git push --all

#Or if you want to push a specific branch to all remotes:
#Replace master with the branch you want to push.
git remote | xargs -L1 -I R git push R master

git config --global alias.pushall '!git remote | xargs -L1 git push --all'
