Homebrew 会将软件包安装到独立目录，并将其文件软链接至
/usr/local。<span class="gp"></span><span class="nb">cd</span> /usr/local <span class="gp"> </span>find Cellar Cellar/wget/1.16.1 Cellar/wget/1.16.1/bin/wget Cellar/wget/1.16.1/share/man/man1/wget.1 <span class="gp">$ </span>ls -l bin bin/wget -> ../Cellar/wget/1.16.1/bin/wget -
Homebrew 不会将文件安装到它本身目录之外，所以您可将 Homebrew 安装到任意位置。
