I am using homebrew-cask to keep my ecosystem of applications up-to-date. It is great when maintaining several computers at home, travel or on the go.
However, when some packages are getting updated (such as Google Chrome), I end up having different concurrent versions installed (and which are seen by the OS):
$ ls /opt/homebrew-cask/Caskroom/google-chrome/
latest stable-channel
This happens when upgrading a cask:
$ ls -l /opt/homebrew-cask/Caskroom/tunnelblick
total 0
drwxr-xr-x 5 foo staff 238 Mar 11 07:42 3.3.0
drwxr-xr-x 5 foo staff 238 May 13 13:53 3.3.2
[13:00:40] foo at bar in ~
$ brew cask install --force tunnelblick
==> Caveats
For security reasons, Tunnelblick must be installed to /Applications and will request to be moved at launch.
