working fine: please don't worry and just ignore them. Thanks!

Warning: Unbrewed dylibs were found in /usr/local/lib.
If you didn't put them there on purpose they could cause problems when

Warning: Homebrew's sbin was not found in your PATH but you have installed
formulae that put executables in /usr/local/sbin.
Consider setting the PATH for example like so
    echo 'export PATH="/usr/local/sbin:$PATH"' >> ~/.bash_profile

Warning: Your Xcode (6.3.2) is outdated
Please update to Xcode 7.2.
Xcode can be updated from the App Store.

Warning: Some keg-only formula are linked into the Cellar.
Linking a keg-only formula, such as gettext, into the cellar with
`brew link <formula>` will cause other formulae to detect them during
the `./configure` step. This may cause problems when compiling those
other formulae.

Binaries provided by keg-only formulae may override system binaries
with other strange results.

You may wish to `brew unlink` these brews:

Error: Unknown command: cask

It's caskroom, all lowercase. Try this:

brew untap caskroom/cask
brew untap phinze/cask
brew update
brew cask install flash-player

[hovancik]

brew is telling me to use Caskroom

brew install flash-player
Error: No available formula with the name "flash-player"
==> Searching for similarly named formulae...
Error: No similarly named formulae found.
==> Searching taps...
These formulae were found in taps:
Caskroom/cask/flash-player-debugger                                                                                    Caskroom/cask/flash-player
To install one of them, run (for example):
  brew install Caskroom/cask/flash-player-debugger

anyway, after running your commands, it works fine now, also brew install Caskroom/cask/flash-player

Ah, I guess taps are case-insensitive. It is @caskroom though (see: the owner of this repo).

Out of curiosity, what was the output of the commands I gave you? My guess is that you either had phinze/cask tapped (defunct) or you had your own branch checked out in caskroom/cask.

[hovancik]

It was caskroom/cask

brew untap caskroom/cask
