I restored my Mac running 10.9 from time machine after a re-install but it appears that the symbolic links under /usr/local/bin for some of the formulas were lost. The formulas are still installed according to brew list $formula but without the links from /usr/local/bin.
(e.g. /usr/local/Cellar/findutils/4.4.2/bin/gfind exists but not /usr/local/bin/gfind).
Is there a "proper" brew-way to reinstate the links from /usr/local/bin or should I just run a simple find.. | xargs ln -s ...?
There are quite a few links under /usr/local/bin for other formulas, perhaps because I executed brew upgrade, but not to all of them.

The update-reset version of this command resets all formulae to be identical to the contents of their remote repositories, deleting any local changes. It is only used as a last-resort effort to fix a problem (it's like unplugging Homebrew and plugging it back in).
Remove a Symbolic Link with unlink The best way to remove a symlink is with the appropriately named “unlink” tool. Using unlink to delete a symlink is extremely simple, you just need to point it at the symbolic link to unlink and remove. As always with the command line, be sure your syntax is precise.
Instead of reinstating the symlinks, the better way to do it would be to use brew link.
For a given binary which isn't in /usr/local/bin, e.g. yasm, run brew unlink yasm && brew link yasm.
You can run this for all of your packages using xargs, like so:
brew list | xargs -I % sh -c 'brew unlink %; brew link %'
