Git via SSH - multiple keys management

In order to use git over ssh, you need ssh keys. When you want to use multiple keys for different domains, you have to know where and how to configure it. I always forget where this configuration file is stored, so here I make a short note about it. Just edit ~/.ssh/config, e.g.:

vim ~/.ssh/config

Then put there something like:

Host github.com HostName github.com IdentityFile ~/.ssh/id_rsa_githubHost gitlab.com HostName gitlab.com IdentityFile ~/.ssh/id_rsa_gitlab

Et viol!
