I missed that this was merged to master a few months ago: [WayBack] macos – Upgrade all the casks installed via Homebrew Cask – Stack Overflow:
December 2017 Update
I thought it would never happen, but there is now finally an official upgrade mechanism for Homebrew Cask (see [WayBack] Issue 3396 for the implementation)! To use it, simply run this command:
brew cask upgrade
However this will not update casks that do not have versioning information (
version :latest
) or applications that have a built-in upgrade mechanism (auto_updates true
). To reinstall these casks (and consequently upgrade them if upgrades are available), run the upgrade command with the--greedy
flag like this:
brew cask upgrade --greedy
It means you do not need manual scripts any more. So you can do without this workaround: [WayBack] GitHub – buo/homebrew-cask-upgrade: A command line tool for upgrading every outdated app installed by Homebrew Cask.
