Improve 'Caskroom location has moved' message

[ChrisJefferson]

So, the current 'caskroom has moved' message tells me I have 'migrate my Casks'. I can read https://github.com/caskroom/homebrew-cask/issues/21913, which tells me I can:

• Do a mv, except that won't work for casks installed before pull request Change artifact behavior to moving instead of symlinking #13966 (how do I find out if my casks fall under that?)

and maybe I won't be able to uninstall without a --force. And there is one comment with 5 hearts: brew cask install --force $(brew cask list). Is that what I should actually do? Because it doesn't seem to actually do anything (I still don't have a /usr/local/Caskroom)

Or for f in ~/Applications/*.app; do oldloc="$(readlink "$f")"; [[ -e $oldloc ]] || ln -sf "/usr/local${oldloc#/opt/homebrew-cask}" "$f"; done? is also there!

Perhaps change the message to give a suggested thing to run, which will make things work.

On a side note, I'm not sure what I need to do, I uninstalled and installed Virtualbox the other day and it didn't go into the new Caskroom folder, is this intentional? Do I need to just move the folders to the new Caskroom location as specified and will that work?

[reitermarkus]

If the old location /opt/homebrew-cask/Caskroom exists, it will still be used.

[matty]

What about other files related to Caskroom in /opt? e.g /opt/vagrant? Have they moved?

[reitermarkus]

/opt/vagrant is not related to this. It may have been installed by Homebrew Cask, but it being there is simply because the pkg installer installed it there.

@reitermarkus : So, how do I make it go away cleanly? Uninstall everything, remove directory, reinstall everything?

I tried doing something like CASKS=$(brew cask list); for i in $CASKS..., but unfortunately the way it outputs doesn't seem to get split by bash properly

That's because you're not doing bash properly 😉

CASKS=($(brew cask list))
for cask in "${CASKS[@]}"; do
  # whatever
done

@jawshooah : Every time I think I've figured out bash :|

Given this new bash-power, I came up with the following, which worked on my computer (You could rm -rf /opt/homebrew-cask/Caskroom if anything is left behind). You should do this a step at a time, not just try cutting+pasting the whole thing in one go (it might, be I don't promise anything

# Grab the casks you have installed
CASKS=($(brew cask list))

# Uninstall everything
for cask in "${CASKS[@]}"; do
  brew cask uninstall --force $cask
done

# Remove the old directory (which is hopefully now empty)
rmdir /opt/homebrew-cask/Caskroom

# Reinstall everything
for cask in "${CASKS[@]}"; do
  brew cask install $cask
done

EDIT: I've edited this based on @jawshooah's comment below (adding --force), to make it easier for anyone who finds this later.

[jawshooah]

You'll want to --force the uninstall to get rid of all installed versions, but yeah, that will probably do what you want.

Closing as solved.
