brew: create install script for all installed packages/casks I am currently planning to reinstall my OS from scratch. Over the years, I installed a LOT OF packages via brew. Obviously, I'd like to reinstall those after setting up the system again, and I want to automate this as much as possible.
Hence my question: How do I list all packages installed via brew, including casks, and how do I create an &quot;install script&quot; from those that will add all added casks for me and then install all packages again?&quot;
Apple Silicon: port all Homebrew packages under /usr/local/opt/ to /opt/homebrew asks a similar question, but doesn't address the creation of a automated install script, rather the port between two architectures.
As basically explained in Apple Silicon: port all Homebrew packages under /usr/local/opt/ to /opt/homebrew (and in https://docs.brew.sh/Manpage#bundle-subcommand):

Create a Brewfile with brew bundle dump
Store the file somewhere safe (flash drive for instance)
Once the computer is set up again, install Homebrew, copy the Brewfile back and run brew bundle install --file /path/to/Brewfile
