根据权限查找文件：
-perm [+|-] MODE
MODE：表示严格匹配，也就是你的文件权限位转换成对应的十进制数字与mode一模一样，那么匹配成功，需要注意的是如果mode给的数字不足3位，那么前面自动添0
[root@VM_168_102_centos tmp]# find /tmp/ -perm 777 | xargs ls -ld srwxrwxrwx 1 root root 0 Aug 22 10:07 /tmp/agent_cmd.sock lrwxrwxrwx 1 root root 13 Aug 22 16:57 /tmp/new_ceshi.sh -> /tmp/ceshi.sh lrwxrwxrwx 1 root root 12 Aug 22 17:00 /tmp/new_wanghan -> /tmp/wanghan
-MODE：表示mode中转换成二进制的1在文件权限位里面必须匹配，比如mode=644那么转换成二进制为110 100 100，而被查找的文件的权限位也可以被转换成一个二进制数，两者在位上为1的部分必须完全匹配，而0则不管。例如被查找的文件的权限为转换成二进制数是111 111 111那么这个比如被匹配，而假如是100 100 100那么则不会匹配。所以这个‘-‘的作用归结起来就是匹配比mode权限更充足的文件

+MODE：与 -mode的区别是+mode只需其中的任意一个1的部分被匹配，-mode是所有1的部分都必须被匹配，同样+mode也不管0位
