linux的文件分区类型查询

在linux下怎样查看文件分区类型？

可以想象到肯定是使用和分区有关的命令和文件才能实现，我尝试了一下有如下几种(如果有什么不对和需要补充的请给我留言)：

1.使用fdisk命令
fdisk /dev/hda
进入fdisk的命令模式，你可以键入m来查看帮助信息
键入p就可以查看hda这个设备的所有分区的文件类型了。
可以键入q来退出fdisk的命令模式

2.使用parted命令
fdisk命令我们经常看到，但是这个命令我们却使用的很少(可能是我自己见识太少了;-))，其实这个命令也是挺强大的，基本上fdisk可以做的parted都可以做到。
parted /dev/hda
进入parted的命令模式，你可以键入help来查看帮助信息。
键入print就可以查看hda这个设备的所有分区的文件类型了。
可以键入quit来退出parted的命令模式

下面是man parted的介绍

PARTED(8)                      GNU Parted Manual                     PARTED(8)

NAME
       GNU Parted - a partition manipulation program

SYNOPSIS
       parted [options] [device [command [options...]...]]

DESCRIPTION
       This  manual page documents briefly the parted command.  Complete docu-
       mentation is distributed with the  package  in  GNU  Info  format;  see
       below.

       parted  is  a  disk  partitioning  and  partition resizing program.  It
       allows you to create, destroy, resize, move and copy ext2, ext3, linux-
       swap,  FAT  and FAT32 partitions. This is useful for creating space for
       new operating systems, reorganising disk usage, and copying data to new
       hard disks.

OPTIONS
       -h, --help
              displays a help message.

       -i, --interactive
              where necessary, prompts for user intervention.

       -s, --script
              never prompts for user intervention.

       -v, --version
              displays the version.

COMMANDS
       [device]
              The block device to partition.

       [command [options]]
              Specifies  a  command  to parted. If no command is given, parted
              will give you a command prompt. Commands are:

              check partition
                     does a simple check on partition.

              cp [source-device] source dest
                     copies the source partition鈙 filesystem on source-device
                     (or  the current device if no other device was specified)
                     to the dest partition on the current device.

              help [command]
                     prints general help, or help on command if specified.

              mkfs partition fs-type
                     make a filesystem fs-type on partition.  fs-type  can  be
                     one of "FAT", "ext2" or "linux-swap".

              mklabel label-type
                     Creates  a new disklabel (partition table) of label-type.
                     label-type should be one of "bsd", "gpt", "loop",  "mac",
                     "mips", "msdos", "pc98" or "sun".

              mkpart part-type [fs-type] start end
                     make  a  part-type  partition with filesystem fs-type (if
                     specified), beginning at start  and  ending  at  end  (in
                     megabytes).  part-type should be one of "primary", "logi-
                     cal" or "extended"

              mkpartfs part-type fs-type start end
                     make a part-type partition with filesystem fs-type begin-
                     ning at start and ending at end (in megabytes)

              move partition start end
                     move  partition  to  start at start and end at end. Note:
                     move never changes the minor number

              name partition name
                     set the name of partition to name. This option works only
                     on  Mac  and  PC98  disklabels. The name can be placed in
                     quotes, if necessary

              print  displays the partition table

              quit   exits parted

              resize partition start end
                     resize the filesystem on partition to start at start  and
                     end at end megabytes

              rm partition
                     deletes partition

              select device
                     choose  device  as  the  current  device  to edit. device
                     should usually be a Linux hard disk device, but it can be
                     a partition, software raid device or a LVM logical volume
                     if that is necessary

              set partition flag state
                     change the state of the flag on partition to state. Flags
                     supported  are: "boot", "root", "swap", "hidden", "raid",
                     "lvm" and "lba".  state should be either "on" or "off"

3.使用mount命令
mount一般用来挂载分区的，其实它也可以用来查看分区类型的。
mount --guess-fstype /dev/hda1
但是这个每次只能查看一个分区

4.使用df命令
df本身就是用来查看分区信息的，但是如果你不加上参数，它是不会列出分区类型的。
df -T
加上-T这个参数，就可以列出所有系统挂载的分区的文件类型信息了

5.查看配置文件
当然你可通过查看配置文件来知道分区的文件类型。
cat /etc/fstab
