Talk:Brace expansion using ranges

Out of curiosity – stepped Alpha seen working in the (unix shell) wild ?

There is a reference to stepped alpha expansions in the increment section of the reference to which I linked in the task description https://wiki.bash-hackers.org/syntax/expansion/brace#increment (referred to without elaboration as an 'interesting feature').

The only reason that haven't implemented it myself (in the current draft of the JS reference implementation) is that it didn't match what I was seeing (macOS Catalina) either in the default zsh command line or in a script with the preamble #!/bin/bash, neither of which expand {a..z..3} to anything other than itself.

I don't think that's a good reason to discourage implementing stepped alpha brace ranges here – they seem a good idea, and we do have that reference – but I wondered if anyone has actually seen stepped alpha expansions work in the wild (where wild is defined as a shell prompt or shell script).
