I know it's a brave new world, but there isn't a single working developer that isn't at least aware of the command line, right?

There are lots of developers that have a build system with ide etc set up for them and never touch the CLI for years. Think iOS and .net

I'd say "aware" and "familiar with" are two totally different groups. And while I'd agree that "aware" seems like it'd approach 100% of the general programmer pop., from my experience "familiar with" is a surprisingly and saddeningly lower than 100% percentage.
