This is my recipe for using git via ssh in the terminal panel of Atom for Windows.

For my own git projects on GitHub and work projects on VSTS, I prefer to use ssh with command line over a GUI. Both places have two-factor authentication enabled. Therefore I have to do these things before I can access my repos via ssh:

  1. generate ssh keys
  2. add them to my accounts
  3. start ssh-agent
  4. ssh-add my ssh keys

GitHub has provided some good help doc for doing those. https://help.github.com/categories/ssh/

The problem is ssh-agent doesn’t save keys. I’ll have to do 3 and 4 every time when I start a new terminal session. It’d be nice to have my terminal automatically do those two steps whenever I start a new session.

I use Atom on Windows. For terminal I usually use a package called Platformio IDE terminal. This way I don’t have to launch another app (like Git Bash or PowerShell). With this package I can set start-up scripts, which is perfect for getting ssh ready in my scenario. Here’s my recipe:

  1. Of course, install Atom and Platformio IDE terminal.

  2. Go to the settings page of this package, set the Shell Override: Shell Override By default on Windows, it uses PowerShell. I found it hard to use SSH in PS, so I switched it to Windows cmd. I also tried Git Bash, but it will not stay inside a panel in Atom. It works, just not pretty.

  3. In the Settings page, write down these ssh commands in the “Auto Run Command” box.
    start-ssh-agent.cmd && ssh-add ~/.ssh/id_rsa
    

    You may need to specify the location of where your ssh keys are stored, if not in the default ~/.ssh/ folder. Also specify the key file names if you have more than one key like I do.

    start-ssh-agent.cmd && ssh-add ~/.ssh/mykey_rsa && ssh-add ~/.ssh/myotherkey_rsa
    

    Shell Override

  4. See that “start-ssh-agent.cmd” above? It comes with Git for Windows. I use this provided script instead of the Linux way work-around eval $(ssh-agent -s) because sometimes the eval thing can get confusing if I’m not using Git Bash.

  5. Now restart Atom and open a terminal panel to test if it works. One way is to use this ssh command:
    ssh -T git@github.com
    

    The other way is to do a git fetch to your repo.
