整理下载tomcat后遇到情况查找资料如下：
下载了onethink，但是文件是这样的：
drwxr-xr-x 15 andy admin 510 10 12 17:48 ./
drwxr-xr-x 39 andy admin 1326 10 12 17:49 ../

-rwxrwxrwx@ 1 andy admin 6271 10 12 17:43 readme.html*
我们可以查看他的意思：
andy@AndyMacBookPro:/usr/local/webdata/onethink$ ls -leO@

这个@代表的时更多的一些属性，具体含义有些老外也不懂，比如这里：
http://superuser.com/questions/28384/what-should-i-do-about-com-apple-quarantine
可以用这个命令来去除这个属性：xattr -d com.apple.quarantine ./*
andy@AndyMacBookPro:/usr/local/webdata/onethink$ xattr -d com.apple.quarantine ./*
andy@AndyMacBookPro:/usr/local/webdata/onethink$ ll

-rwxrwxrwx 1 andy admin 6271 10 12 17:43 readme.html*
后来进入目录发现目录下面的文件还是带有@属性，我们到根目录加一个-r就好了：xattr -d -r com.apple.quarantine ./*
