问题描述
重新安装后，我从时光机恢复了运行10.9的Mac，但似乎某些公式的/usr/local/bin下的符号链接丢失了.仍根据brew list $formula来安装公式，但没有/usr/local/bin的链接.
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.
(例如/usr/local/Cellar/findutils/4.4.2/bin/gfind存在，但/usr/local/bin/gfind不存在).
(e.g. /usr/local/Cellar/findutils/4.4.2/bin/gfind exists but not /usr/local/bin/gfind).
是否存在一种正确"的brew方法来恢复/usr/local/bin中的链接，还是应该只运行一个简单的find.. | xargs ln -s ...?
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 ...?
在/usr/local/bin下有很多其他公式的链接，可能是因为我执行了brew upgrade，但不是全部链接.
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.
推荐答案
代替恢复符号链接，更好的方法是使用brew link.
Instead of reinstating the symlinks, the better way to do it would be to use brew link.
对于不在/usr/local/bin中的给定二进制文件，例如yasm，运行brew unlink yasm && brew link yasm.
For a given binary which isn't in /usr/local/bin, e.g. yasm, run brew unlink yasm && brew link yasm.
您可以使用xargs对所有软件包运行此命令，如下所示:
You can run this for all of your packages using xargs, like so:
brew list | xargs -I % sh -c 'brew unlink %; brew link %'
