Catalina Update Issue, Terminal Question

I had problems updating Catalina this morning on my MacBook Air, so had to go into Recovery & reinstall from the internet. Now I have a message from Terminal on my screen:

"The default interactive shell is now zsh.

To update your account to use zsh, please run `chsh -s /bin/zsh`.

For more details, please visit https://support.apple.com/kb/HT208050"

I'm not a techie, so this surprises me that I have to do this. I can follow the instructions, but after a painful morning fearing I lost all my emails & photos, I'm afraid to do anything else. (Yes, I've learned about TimeMachine & now need to get a backup device). Thanks for any advice!

Reboot away.

Previously-created logins have the login shell set to bash.

Newly-created logins now get the zsh shell.

Those on bash get the diagnostic, and can ignore thar, suppress that, or migrate off bash.

bash on macOS isn’t being updated (and likely due to software copyrights), and has been falling behind current bash for a while.

That zsh-related message is a normal display for Catalina as the zsh command shell replaced the bash shell, and is unrelated to whatever else might have happened.

Thank you so much! I was afraid to reboot and not be able to access my files if I rebooted unless I updated my account as instructed (run `chsh -s /bin/zsh`)
