microsoft is leveraging FOSS Linux to get Mac users. I think it's a real smart move. The author points to using grep and Xargs and some other tools to quickly update a package. That's the key here. These bash/Linux utilities are productivy boosters for all the Linux and Mac/bsd people out there. I can't imagine living without them and they're necessary for any system I develop on (which is currently a Mac).
Its actually kind of interesting that we dont have a literal "standard base" of tools that any OS should supply. (unless I am missing something) But it would make sense that certain things should be doable on literally any computer. grep, find, vi, edit, etc... etc... I cant come up with a complete list - but it would be great to start that direction.
