推荐答案

# stat tool
  File: `tool'
  Size: 4096            Blocks: 8          IO Block: 4096   directory
Device: 801h/2049d      Inode: 671689      Links: 3

# ls -l /dev/sda* 
brw-rw---- 1 root disk 8, 0 2010-08-16 14:43 /dev/sda
brw-rw---- 1 root disk 8, 1 2010-08-16 14:43 /dev/sda1
brw-rw---- 1 root disk 8, 2 2010-08-16 14:43 /dev/sda2
brw-rw---- 1 root disk 8, 5 2010-08-16 14:43 /dev/sda5

在示例中，工具"(801h)位于/dev/sda1中(主要设备号为8，次要设备号为1)，这是/dev/sda中的第一个分区.

In the example, 'tool'(801h) is in /dev/sda1(major device number is 8, minor device number is 1), that's first partition in /dev/sda.
