this just showed up What is ZSH? Do I need it? Why? And it bugs me
I don't understand what this is all about. It just showed up in my dock, and I don't like it. ZSH... what is it, why do I need it? It bugs me.
Thanks,

Question marked as
Apple has been shipping the unsupported and ancient bash 3.2.57 shell with macOS for more than a decade. With Catalina and Big Sur, Apple chose to switch to the MIT licensed, and supportable zsh shell as the default shell in the Terminal. The old bash shell is still available if you prefer to continue using it.
There are two approaches to the issue. Don't switch to the new zsh shell and gag that Terminal message by editing your bash startup file (/Users/username/.bash_profile) and add the following line:
export BASH_SILENCE_DEPRECATION_WARNING=1
or switch to the new zsh shell by running the recommended command:
sudo chsh -s /bin/zsh
Enter your admin password at the prompt and press return. The characters are not echoed as you enter them.
In either case, the message that appears when you launch the Terminal will disappear.
