Such as Fish, nushell, Elvish, or the project I help maintain, “murex”
Unfortunately though, it’s not generally that hard to switch between different shells. I hear the argument you made a lot from other people too and yet we all acknowledge you should be able to code in Bash and a “proper” programming language (Python, Go, JavaScript, C, Rust, whatever). In fact I’ve learned probably 2 dozen languages in my career and it’s rare when I need to pause and remind myself how to do x in y.
Or to put it another way: you don’t say “I’m not going to use $IDE on my dev machine because I’m stuck with vi on the remote server”.
But if people don’t feel comfortable working in two different shells and that is the dealbreaker for using murex, or any other alternative shell, then I’m not going to hold that against them. Everyone has their own preference when it comes to workflows and productivity tools.
Ruby replaced all my shell needs. Almost 25 years ago. I even have a shell written in ruby (it handles both bash-like behaviour as well as ruby code as-is); admittedly it is not quite perfect for everything, but I improve on it steadily. And it works on Windows too, which was one reason I wrote it in the first place (need to have it work via cmd.exe as-is).
Never looked back to shell. It is too awful to use.
Powershell is, as I understand it, not available on Linux but is omnipresent on Windows, so hopefully the windows folks can use it like they would bash.
Do note that Windows Powershell and Powershell are NOT the same. The following does work in Powershell, but not Windows Powershell.
echo hello && echo hello
Specifically Windows Powershell does not support `&&` or `||` (the main difference I immediately notice) and probably a lot of other things are different.Because Windows is tied together through APIs and databases and not text files (unlike Linux), everything is text is not as useful as something that can talk objects. And a lot of Windows is object oriented, from the window message dispatching system through COM and down to NT's object manager.
