When you get a new Macbook Pro with M1 chip you get an old version of Bash.
Bash isn’t old. It’s still being maintained. It has millions of Linux and Windows users. Here’s how to put the newest version of Bash back inside your MacOS box.
Prerequisite: Install Homebrew. (Install iTerm2 for good measure.)
Install Bash and the bare minimum of things things you would expect it to have:
brew install bash bash-completion lesspipe
Verify that it’s installed:
which -a bash

Add it to your /etc/shells
file:
sudo nano /etc/shells

Change your default shell to the new Bash:
chsh -s /opt/homebrew/bin/bash
Create a .profile
and .bashrc
that resembles what you would see in Ubuntu 22.04’s /etc/skel
folder:
From here, create your .bash_aliases
and make all the other adjustments you’ve been doing since 1989… Bash not dead!
