homebrew.global.autoUpdate

Whether to enable Homebrew to auto-update itself and all formulae when you manually invoke commands like brew install, brew upgrade, brew tap, and brew bundle [install].

Note that Homebrew auto-updates when you manually invoke commands like the ones mentioned above if it's been more than 5 minutes since it last updated.

You may want to consider disabling this option if you have enabled, and disabled, if you want to ensure that your installed formulae will only be upgraded during nix-darwin system activation, after you've explicitly run brew update.

Implementation note: when disabled, this option sets the HOMEBREW_NO_AUTO_UPDATE environment variable, by adding it to .
