alt Hacker NewsEverything I wrote works in bash and zsh. I think this is going to be fine for the vast majority of people. Tbh, I'm not sure what isn't portable, or at least not portable for everything that the curl-pipe-bash pattern doesn't already work for.

I'm not sure either but some of those things are bashisms. `<(...)` is a bashism and won't work in some shells. Honestly I ONLY use bash, so it's fine for me, but since you seem to be a pedantic person I thought you should consider trying to solve that puzzle too. Someone might want to copy and paste your command into csh, tcsh, zsh, sh, or ksh. Some of these may support bashisms and some don't. I haven't tried to investigate further either, even to the point of talking to an AI about it, but if you want max nerd cred then you can shoot for it. Keep in mind that csh/tcsh is not entirely POSIX compliant, but it is default on some BSDs.

`curl foo.sh | bash` works with any shell as long as bash is installed. `bash <(curl foo.sh)` doesn't work on shells that don't have that process substitution syntax (like fish, and I think nushell)
