How to upload git repo to the server directly without a intermediate repository

push_git_to_server.sh

# We are in a folder with local git repository
pwd 

# We need to create an empty repo on the server
# We want to checkout another branch because
# git prevents you from pushing to the current checked branch, which is master by default
ssh <user>@<host> 'mkdir repo && cd repo && git init && git checkout -b local'

# Add remote repo
git remote add server <user>@<host>:repo
# Push master or whatever you want
git push server master

# Updates files tree to match your pushed branch
ssh <user>@<host> 'cd repo && git reset --hard master'

# That's it. You have a copy of git repository on the server without any intermediate repository
