Save the following files to GitHub:
Package Control.sublime-settings
Terminal.sublime-settings
I used the following, after the SublimeText3 Installation, to install the package manager, and then copy the two files above to predefined directories:
echo Install my Sublime Text 3 packages ...
cwd=$(pwd)
mkdir -p ~/.config/sublime-text-3/Installed\ Packages
cd ~/.config/sublime-text-3/Installed\ Packages/
wget --quiet https://packagecontrol.io/Package%20Control.sublime-package
mkdir -p ~/.config/sublime-text-3/Packages/User
cd ~/.config/sublime-text-3/Packages/User/
wget --quiet https://github.com/rudolfb/ubuntu-elixir-elm-install-shell-script/raw/master/sublime-text-3/Package%20Control.sublime-settings
wget --quiet https://github.com/rudolfb/ubuntu-elixir-elm-install-shell-script/raw/master/sublime-text-3/Terminal.sublime-settings
# Revert back to previous directory
cd $cwd
When you start SublimeText then SublimeText will see the two files and downlaod any packages referenced in those files.
But as @keithking mentioned, you can use the workflow described at packagecontrol.io/docs/syncing link.
