brew: unlink and re-link all formulas and kegs

brew-unlink_relink.sh

ls -1 /usr/local/Library/LinkedKegs | while read line; do echo $line; brew unlink $line; brew link --force $line; done
brew list -1 | while read line; do brew unlink $line; brew link $line; done

👍

Tried: ls -1 /usr/local/Library/LinkedKegs and got ls: /usr/local/Library/LinkedKegs: No such file or directory.

Used: brew list | while read line; do echo $line; brew unlink $line; brew link --force $line; done and that worked.
