Just Git push with SSH
I'm making a note of this because I often forget it when pushing to GitHub.
Assume that the key has already been issued. If not,
ssh-keygen -t rsa -b 4096
do this.
cat ~/.ssh/id_rsa.pub
Copy this and paste it into GitHub's SSH key settings.
And this is also the reason I'm writing this time,
ssh -T git@github.com
I completely forgot this. Once set up, it's easy to forget afterwards.
That's all.
