brewupdate is a launchd agent to update homebrew formulae automatically every 7 days at 11 AM (local time).
brewupdate will brew update, brew upgrade, and brew doctor so you may want to adjust this behaviour inside brewupdate.sh given an upgrade may break something dependent on a certain version.
Run the following command in the terminal:
$ curl -L https://github.com/heitortsergent/brewupdate/raw/master/brewupdate-install.sh | bashTo manually install brewupdate:
Copy brewupdate.sh to your /usr/local/bin folder, then the plist to ~/Library/LaunchAgents and run the command launchctl load ~/Library/LaunchAgents/net.brewupdate.agent.plist to load the LaunchAgent into the launchd manager.
Here is a quick rundown:
# install terminal-notifier to get a nice user notification when the script runs
$ brew install terminal-notifier
# download repo and copy files to correct folders
$ git clone https://github.com/heitortsergent/brewupdate.git && cd brewupdate
$ cp brewupdate.sh /usr/local/bin
$ mkdir ~/Library/LaunchAgents
$ cp net.brewupdate.agent.plist ~/Library/LaunchAgents
# add log paths to .plist file
$ defaults write ~/Library/LaunchAgents/net.brewupdate.agent.plist StandardOutPath $HOME/Library/Logs/Homebrew/brewupdate/brewupdate.log && defaults write ~/Library/LaunchAgents/net.brewupdate.agent.plist StandardErrorPath $HOME/Library/Logs/Homebrew/brewupdate/brewupdate-error.log
$ mkdir -p $HOME/Library/Logs/Homebrew/brewupdate
# load the LaunchAgent
$ launchctl load ~/Library/LaunchAgents/net.brewupdate.agent.plistIf you installed a previous version of brewupdate, unload the loaded LaunchAgent, copy the new brewupdate.sh and/or the new agent to ~/Library/LaunchAgents, and load the copied LaunchAgent.
Here is a quick rundown:
$ launchctl unload ~/Library/LaunchAgents/net.brewupdate.agent.plist
$ cp brewupdate.sh /usr/local/bin
$ cp net.brewupdate.agent.plist ~/Library/LaunchAgents
$ launchctl load ~/Library/LaunchAgents/net.brewupdate.agent.plist
Since OS X 10.8, Apple removed the redirection of stdout and stderr to system.log.
When the script runs, it'll show a notification using the terminal-notifier command-line tool. The logs are being kept inside $HOME/Library/Logs/Homebrew/brewupdate/brewupdate.log and errors inside $HOME/Library/Logs/Homebrew/brewupdate/brewupdate-error.log. You can change that by editing the StandardOutPath and StandardErrorPath properties inside the net.brewupdate.agent.plist file (don't forget to unload and load after making the changes).
