user launch agent to update & upgrade Homebrew daily

README.md

org.boneskull.homebrew-upgrade

This launch agent will automatically update & upgrade Homebrew every day. Upon success, it will send a notification.

UPDATED Nov 7 2023

Installation

1. Install Homebrew.
2. Install terminal-notifier. Execute brew install terminal-notifier.
3. Copy the .plist file in this gist into ~/Library/LaunchAgents/.
4. Execute launchctl load ~/Library/LaunchAgents/org.boneskull.homebrew-upgrade.plist. Do not run this command with superuser privileges.

Notes

• Clicking on the thing should open the log file in whatever opens .log files by default (usually Console.app)
• I've had something similar working from Yosemite through Sonoma.
• This launch agent will run at load, and every 24h thereafter.

TODO

• Report errors
• Better interaction
