xshell怎么使用啊？

命令是： fdisk -l
Disk /dev/sda: 10.7 GB, 10737418240 bytes
255 heads, 63 sectors/track, 1305 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00044938
  Device Boot      Start        End      Blocks  Id  System
/dev/sda1  *          1        638    5120000  83  Linux
Partition 1 does not end on cylinder boundary.
/dev/sda2            638        893    2048000  83  Linux
Partition 2 does not end on cylinder boundary.
/dev/sda3            893        1020    1024000  82  Linux swap / Solaris
Partition 3 does not end on cylinder boundary.
/dev/sda4            1020        1306    2292736    5  Extended
/dev/sda5            1021        1306    2291712  83  Linux

正确命令应该是fdisk -l这样吧
