"Run X Windows and you have the same thing on Linux as on Windows." No you don't. X Windows is still run from a shell. The Windows GUI, by contrast, is not. Any application run in Linux or Solaris or whatever can drop down to the shell. And if I run an application from a terminal, I can take advantage of that. Not so with Windows. "Anyway, without any IDE and with just Notepad knowing a bit of .NET you could create yoru own functions where it isn't enough." I've written PoSH modules before. I'm pretty familiar with the process. I don't know what point you're trying to make. "Why do you think Linux CLI tools are complete ?" Because in the Unix environment, the CLI tools have been the primary admin interface for the past 40+ years. In Linux, the CLI comes first and the GUI is an afterthought. In Windows, it's the other way around. If you think that's changing, great. But I work on Windows in my day to day work, and regularly write Powershell so I've got a good feel for the difference.
