Use Git to manage Kerbal Space Program saves, ships and CKAN mods

git-ksp-ckan.md

This example show how to manage two KSP installs, like one on your Windows gaming rig and one on your Mac, as they were one.

First, create a GitHub repo called git-ksp-ckan under your own username

Then, if your Mac is the starting point:

cd ~/Library/Application Support/Steam/SteamApps/common/Kerbal Space Program
git init
cp CKAN/installed-default.ckan CKAN/should-be-installed.ckan
git add CKAN/should-be-installed.ckan
echo "saves/scenarios" >> .gitignore
echo "saves/training" >> .gitignore
git add .gitignore
git add saves

Create a commit with the date and time as message

git commit -a -m $(date "+%Y%m%d%H%M")
git remote add origin https://github.com/<yourusername>/git-ksp-ckan.git

Push the changes up to GitHub

git push -u origin master

Now on your Windows PC start "Git Bash"

First we make sure ckan.exe is in the KSP folder

cd "/c/Program Files (x86)/Steam/SteamApps/Common/Kerbal Space Program"
cp /c/Users/<yourusername>/Downloads/ckan.exe .
ckan.exe update

Then we add our Git repository and fetch the files

git init
git remote add origin https://github.com/<yourusername>/git-ksp-ckan.git
git fetch --all
git reset --hard origin/master

Now it's time to make sure CKAN is correctly up to date

ckan.exe install -c CKAN/should-be-installed.ckan

You should now be able to start KSP, see your old saves and ships, and have all the right mods installed.
