  -f, --file-system     display file system status instead of file status
  -c  --format=FORMAT   use the specified FORMAT instead of the default;
                          output a newline after each use of FORMAT

  %G   Group name of owner
  %h   Number of hard links

范例：
不帶參數，顯示文件inode信息

# stat linuxeye2.txt
  File: `linuxeye2.txt'
  Size: 26              Blocks: 8          IO Block: 4096   regular file

Change: 2013-06-19 17:50:11.000000000 +0800

帶參數，stat查看文件大小

# stat -c %s linuxeye2.txt
26

帶多個參數，顯示文件多個信息

# stat -c'%Z| %s' linuxeye2.txt
