If you're here, you already know what Homebrew is, and how annoying it is that its default behaviour is to update EVERYTHING when you just want to update or install one thing. Let's not even mention that this behaviour has the potential to inadvertently break other software on your machine. One has to ask, why is this even the default behaviour.
The good news is that there is a flag that you can set
Per call
HOMEBREW_NO_AUTO_UPDATE=1 brew install <package>
System-wide
# ~/.bashrc or ~/.zshrc export HOMEBREW_NO_AUTO_UPDATE=1
Here's to not having to wait a long time just to end up breaking your Mac 🍻
