echo "$install/bash-config.sh"

This script sets up an SSH key, which is copied to both GitHub and your webhost. It also does some basic git configuration and allows you to pull down a private setup repo to a custom location.

Requirements

macOS High Sierra -- it might work on Sierra, but not tested

How To Install

Warning: This script is NOT stable yet. Run at your own peril.

1. Run this command in Terminal to download the setup gist to your desktop and make it executable:

f=~/"Desktop/Start Setup"; curl -Lo "$f" https://git.io/vpqln && chmod +x "$f"

2. Configure your install at https://setup.ginn.io. Follow the prompts.
3. Click "Copy to Clipboard" to capture the values of all set fields.
4. Double-click the setup.sh script on your desktop. This will save a ~/.setup file with the configuration data on your clipboard. Any missing info will be requested during the setup process.

Known Issues

• This script asks for your password twice, since I haven't decided which password retrieval method to use.
• The web server asks for your password. I've discovered the ssh command will not let you include a password. Technically, though, the server section doesn't have to be included in this gist...so we could likely install sshpass after brew is installed.
