硬盘相关命令
查找硬盘上，大小超过指定值的文件
Linux与solaris各版本均一致
命令：$ find /
-xdev -size +9000000c
-exec ls -l {} \; 或
find / -xdev -size +9000000c
注： "c" 表示字符，一个字符占用一个字节。1000000c 约为 1 MB。
(+) 表示 "大于" 给出的数字。
(-) 表示 "小于" 给出的数字。
"-xdev" ，避免查找文件系统 Mount Point 下的目录。
执行时间：1 ~ 2 s
*** 执行结果1：
$ find . -xdev
-size +9000000c
-exec ls -l {} \;
