linux查看分区类型 z

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.
