I asked this question on SO, which I ended up answering myself after a journey of discovery into the world of git and bash. The info I gathered seemed good content to finally write my first blog post - which I'm sure is cool - but is it cool to then add a link from your question or answers to that blog post?
I think yes as long as you don't 'take away' from SO, the question/answers should retain all the necessary info. But the 'article' style of a blog post allows for a better formatted read - rather than the somewhat random answers/comments to a question on SO - and in this case feels like a better way to package the info. Apart from the excuse for a first blog post :)
