You could also use which like:

exists() { [ ! -z `which "$1"` ]; }

I hadn't see that. Good catch, and definitely more comprehensive.

good stuff. I learned that the new capistrano (3.0) doesn't have deploy:cold anymore. You can just deploy. But it means you'll need a db:create to happen somewhere before your first deployment.

looks like this could be merged with https://coderwall.com/p/_ppnlg for good time fun
