Upgrade outdated brew casks. One liner, and the ”official” way to do it without using different hacks or scripts. However, it does not really replace some scripts out there, as in-app updates is not seen by Homebrew.

# Upgrade / Update outdated casks installed.

	brew upgrade $(brew outdated --cask --greedy --quiet)

brute force method...

brew cask reinstall --force `brew cask outdated --greedy`

$ brew cask reinstall `brew cask outdated`

Error: This command requires a Cask token.

The cask command doesn't exist anymore. This works: brew upgrade $(brew outdated --cask --greedy --quiet)

Thanks (was a long time i was here)!

I had to use brew upgrade --cask $(brew outdated --cask --greedy --quiet).

For example, brew upgrade docker and brew upgrade --cask docker have a different meaning.
