Note: make sure to change NODEKODOMAIN to the one for your project.

export NODEKODOMAIN="pants-pants-evolution.no.de"
alias push_and_restart="git push origin master && git push joyent master && ssh node@$NODEKODOMAIN 'source .profile && node-service-restart'"

After adding this,

source $HOME/.bashrc

and then you can

push_and_restart

in your git repo and it should all "just work" njoy !
