I try to stay on the default shells of environments as much as possible, especially as that makes life easier when needing to work on an non-customised system.
Apple switched back from an ancient latest GPLv2 version 3.2 of bash (they regard newer GPLv3 as toxic to their revenue stream¹), introduced MIT-license based zsh and introduced a bash nag screen a few years ago forcing users to switch. Suppressing that message reliably is trickier than you might think².
After so many years of bash, I still stumble over things that zsh does differently: [Wayback/Archive] command line – Why does a cURL request return a percent sign (%) with every request in ZSH? – Stack Overflow (thanks [Wayback/Archive] Travis and [Wayback/Archive] zaTricky) is a “feature” with a simple workaround for cURL:
This is a zsh feature that prints a percent-and-newline after a command completes if that command does not already include a newline at the end of its output. If zsh did not do this, you would either not ever notice the fact that the command didn’t print a newline – or you’d see zsh’s command prompt not start on the margin and think it was a bug in zsh.

Since the above example now writes a redirect messages (good bye HTTP, welcome HTTPS), and I very much dislike short command-line parameters, here is version with the long form of the [Wayback/Archive] curl -w or --write-out parameter :
