More, less, and a story of typical Unix fossilization
I've used Linux for a decade-and-a-half, but I've never totally loved the shell, because of the need to learn this sort of pointless arcana. PowerShell was a massive step forward, and I had hoped that an Open Source, cross-platform equivalent would develop so that we could get past the current local maxima of 1970s-era design.It's rather weird that the Open Source equivalent of PowerShell is now...PowerShell. Even if you don't like Microsoft or .NET, if you care about shells I'd recommend trying out PowerShell Core for an hour or two. It's only  when you use it for a bit that you start to realize that you can guess commands based on the rules and actually be right and how big an improvement that actually is, rather than the current UNIX method of having to memorize more and more obscure trivia in order to get the computer to do what you want. I'm not sure if PowerShell itself is a long-term answer because of the .NET and Microsoft dependencies, but it gets lot of things right.It's time we dropped the "Bash is good enough" arguments. There are now new Linux users starting every day, and asking them to learn that less is better than more is not funny.
