eval ssh-agent -s
ssh-add ~/.ssh/id_rsa_rajesh.cotocus

I had to change the [remote "origin"] / url field in my local .git/config to use the Host defined in .ssh/config in order for this to work, i.e.,

[remote "origin"]
        url = git@github.com-activehacker:activehacker/gfs.git
Without that modification, git would just try to use my default ssh key.Code language: JavaScript (javascript)
