From zsh back to bash

From zsh back to bash

How do I find out which shell options I have in a zsh terminal?
How do I set the standard shell (in an iMac from 2017) to be bash instead
of zsh ?
"Why?" you maybe ask. To get the terminal do bash commands (=all) is the
answer!

To hopefully answer your first question, the following should output all
the options and whether they are  set or not.

   L=${#${(Ok@)options//?/X}[1]}  # get max option char length for output
alignment
   for opt (${(ok)options}) print ${(r.L.. .)Ele} ${options[$opt]}

Not a Mac user so I will let someone else respond to the other questions.

Jim Murphy

Assuming you mean "which shells you have available", this command
lists the shells provided by macOS (assuming /etc/shells hasn't
been modified):

	% cat /etc/shells

Presumably you know about any shells that you've installed yourself.

Assuming you mean "default interactive shell", follow these
instructions but select bash instead of zsh:

https://support.apple.com/en-us/102360

Note that macOS's /bin/bash is very old.  If you want to use another
bash, you may have to adjust the instructions (e.g., run "sudo chsh
-s /path/to/newer/bash" instead of the unprivileged "chsh -s
/bin/bash").

How to obtain another bash is left as an exercise for the reader.
