When I started my first real job in IT (almost 15 years ago) it felt a bit odd. At that time I was spending most of my time on Linux, yet my work required mainly Windows skills. My work colleague knew my background so I got task that supposed to be “gateway drug” to get me back on Windows side: updating backup script that was written in batch. Pure batch: I was not allowed to install any of the *nix tool’s ports to aid me in this project. And there were few significant requirements, and new one arrived every now and than.
