linux查看分区类型：
fdisk -l
df -Th
parted
----------------------------------------详解-------------------------------------
fdisk -l 命令查看一下
# fdisk -l
Disk /dev/sda: 12.8 GB, 12884901888 bytes
255 heads, 63 sectors/track, 1566 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x0003bbd5
Device Boot Start End Blocks Id System
/dev/sda1 * 1 1494 12000523+ 83 Linux
/dev/sda2 1495 1566 578340 5 Extended
/dev/sda5 1495 1566 578308+ 82 Linux swap / Solaris
查看硬盘是什么分区，使用fdisk -l，但是看不到文件系统类型，只能看到分区类型，以Redhat 9为例：
[root@redhat9 root]# fdisk -l
Disk /dev/sda: 8589 MB, 8589934592 bytes
255 heads, 63 sectors/track, 1044 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/sda1 * 1 13 104391 83 Linux
/dev/sda2 14 1012 8024467+ 83 Linux
/dev/sda3 1013 1044 257040 82 Linux swap
df -Th 命令
友好一些，容量大小是以易读的方式显示的，而且它是显示所有分区，并不是一个分区。这个命令最方便。
[root@redhat9 root]# df -Th
Filesystem Type Size Used Avail Use％ Mounted on
/dev/sda2 ext3 7.6G 2.3G 4.9G 32％ /
/dev/sda1 ext3 99M 9.3M 85M 10％ /boot
none tmpfs 62M 0 62M 0％ /dev/shm
parted
倒是有点复杂了，因为它的功能很强，redhat 9中的parted不支持-p参数，但是用parted命令进入后可以用p命令显示出当前的磁盘分区和文件系统情况：
# parted

Using /dev/sda
Information: The operating system thinks the geometry on /dev/sda is 1044/255/63. Therefore,
cylinder 1024 ends at 8032.499M.

ubuntu下使用parted：
root@bai-desktop:/home/bai# parted
