Suppressing “The default interactive shell is now zsh” message in macOS Catalina

  • 0

I know Catalina uses zsh as the default login shell and interactive shell, but it is very annoying when I open iTerm.app or run command with /bin/bash, it shows verbose message like below:

$ /bin/bash
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.

The support document the message links to is https://support.apple.com/kb/HT208050

How can I hide the verbose logging? I do not want to be reminding that the “default interactive shell is now zsh” every time I open Terminal.

    I found the solution on reddit. The solution is also mentioned in the “How to use a different shell without changing the default” section of the Apple support article mentioned in the bash warning: https://support.apple.com/en-us/HT208050/.

    Add:

    export BASH_SILENCE_DEPRECATION_WARNING=1

    to $HOME/.bash_profile, $HOME/.profile or $HOME/.bashrc and restart iTerm. After that, the warning message will be gone.
