Autoupgrade the software installed with brew

If you use brew as package manager on macOS, it is interesting to autoupdate the software installed with this tool.

The autoupdate subcommand does this job. To automatically run brew update every 24 hours, you can use this command:

brew autoupdate start

If you use the --upgrade  parameter, you are going to automatically run brew upgrade, too.

brew autoupdate start --upgrade
