When I answer questions on quora about learning Linux and other UNIX derivative, I still point them at their book: *The Unix Programming Environment <http://www.amazon.com/gp/product/013937681X?ie=UTF8&tag=catv-20&linkCode=as2&camp=1789&creative=9325&creativeASIN=013937681X>* I would say, if the can login into the system and complete the exercises in UPE without having to make changes, you are pretty close to Doug's "Universal UNIX" environment. And if you can use the tools, without having to think about them and they pretty much are what you rely upon everyday, you are getting close to my ideal of 'good taste.' Clem
