That's why i mentioned Linux.

On streets and from companies you will get totally different answers.

People working on Windows have left CLI long back, many newly trained freshers don't even know what DOS is and how to use it.

Just yesterday I had a friend (working at a big printing company) calling me to help him out. He had been using Windows all his life, must have clicked on "Command Prompt" under Accessories accidentally, and he was scared to death. Told me "something happened to my windows, all black screen with just a C:\". He was so scared and believed his machine is dead and all data lost. After I helped him to get out of command prompt, he asked what was that and what was C:\ . And he has been using windows for more than 8 years now.
