Brew Doctor Symlinks Prune

After running a brew update, it is best to next run brew doctor. Sometimes you may run into broken symlinks message like after an operating system or xcode update for example.

$ brew doctor

Please note that these warnings are just used to help the Homebrew maintainers
with debugging if you file an issue. If everything you use Homebrew for is
working fine: please don't worry and just ignore them. Thanks!

Warning: Broken symlinks were found. Remove them with `brew prune`:
  /usr/local/bin/csslint
  /usr/local/lib/node_modules/yo/node_modules/.bin/fullname
  /usr/local/lib/node_modules/yo/node_modules/.bin/opn
  /usr/local/lib/node_modules/yo/node_modules/.bin/repeating
  /usr/local/lib/node_modules/yo/node_modules/.bin/user-home

$ brew prune

Error: Permission denied - /usr/local/share/man/man8/prlexec.8

$ brew doctor

As mentioned in my post Homebrew Doctor Warning, running this command will correct this problem and the warning will go away.
sudo chown -R $(whoami) /usr/local/share/man/man8

Now rerun brew prune.

$ brew prune
Pruned 1 symbolic links and 1 directories from /usr/local

After your password is entered correctly run brew doctor again. Now you should finally get: Your system is ready to brew.
