fdisk -l 看是这样的

Disk /dev/sda: 10.7 GB, 10737418240 bytes
255 heads, 63 sectors/track, 1305 cylinders, total 20971520 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes

/dev/sda2 19924992 20971519 523264 82 Linux swap / Solaris

但是为什么free的时候看，swap 是0呢

total used free shared buffers cached
