How to specify custom ssh key while git clone from github

If you need to provide some custom ssh key while cloning your repository from github (or pulling, whatsoever), run this command:

ssh-agent $(eval `ssh-agent -s`; ssh-add ~/.ssh/{your-custom-keyfile}; git clone [email protected]:{username}/{repo-name}.git .)

Please note, you should replace {strings} with plain string values!
