An easy, convenient way to automatically update Homebrew.
This script will run
brew update in the background once every 24 hours by default.
brew upgrade and
brew cleanup can also be handled automatically but
are optional flags. If you have
terminal-notifier installed you can
also request desktop notifications when this command runs.
Installing this command
brew tap domt4/autoupdate.
brew autoupdate --start [interval] [--upgrade] [--cleanup] [--enable-notification]: Start autoupdating either once every interval hours or once every 24 hours. Please note the interval has to be passed in seconds, so 12 hours would be: brew autoupdate --start 43200. If --upgrade is specified, autoupdate will also upgrade your installed formulae. If the Caskroom exists locally Casks will be upgraded as well. If --cleanup is specified, autoupdate will also automatically clean brew's cache and logs. If --enable-notification is specified, autoupdate will send a notification when the autoupdate process has finished successfully, if terminal-notifier is installed & found. autoupdate --stop: Stop autoupdating, but retain plist & logs. autoupdate --delete: Cancel the autoupdate, delete the plist and logs. autoupdate --status: Prints the current status of this tool. autoupdate --version: Output this tool's current version.
This Vs brew's built-in autoupdate mechanism
This command mostly exists to ensure Homebrew is updated regardless of whether
brew or not, which is the primary difference from the autoupdate
mechanism built into
brew, the latter requiring a user to explicitly run
brew tap or
If you run
brew commands regularly yourself, you may wish to consider using
the built-in autoupdate mechanism, which can be instructed to autoupdate less
often or disabled entirely. If you wish to update every 24 hours using the
built-in autoupdate mechanism set this in your environment:
or if you wish to disable the built-in autoupdate mechanism entirely:
Please note that Homebrew themselves slightly frown upon people disabling the built-in autoupdate mechanism.
