Not really. They’ve been on the stabilising path for about two years now, removing stuff like dataframes from the default feature set to be able to focus on stabilising the whole core language, but 1.0 isn’t out yet and the minor version just went three digits.

And it’s good that way. The POSIX CLI is a clusterfuck because it got standardised before it got stabilised. dd’s syntax is just the peak of the iceberg, there, you gotta take out the nail scissors and manicure the whole lawn before promising that things won’t change.

Even in its current state it’s probably less work for many scripts, though. That is, updating things, especially if you version-lock (hello, nixos) will be less of a headache than writing sh could ever be. nushell is a really nice language, occasionally a bit verbose but never in the boilerplate for boilerplate’s sake way, but in the “In two weeks I’ll be glad it’s not perl” way. Things like command line parsing are ludicrously convenient (though please nushell people land collecting repeated arguments into lists).
