Latest bash on Catalina with MacPorts
Install XCode via the App Store.
Install XCode command-line tools:
xcode-select --install
Change your shell from zsh to the ancient version of bash that Apple supplies:
chsh -s /bin/bash
Install MacPorts.
Open a new terminal window, which will now have MacPorts paths in $PATH.
Install latest bash with MacPorts:
sudo port install bash
Add the new bash as a valid shell:
sudo vi /etc/shells
Add /opt/local/bin/bash to the list of valid shells.
Change your shell to the new bash:
chsh -s /opt/local/bin/bash
Open a new terminal window and verify that in fact, you are running the latest bash:
$ bash --version
GNU bash, version 5.0.16(1)-release (x86_64-apple-darwin19.3.0)
Bash scripts with #!/bin/bash
at the top will still run bash 3.2.57. Using env is one way to get around this; read Daniel's article below.
Note that nobody is saying zsh is not cool.
