一、sfdisk -l
[root@localhost ~]# sfdisk -l
Disk /dev/sda: 4863 cylinders, 255 heads, 63 sectors/track
Units = cylinders of 8225280 bytes, blocks of 1024 bytes, counting from 0
Device Boot Start???? End?? #cyls??? #blocks?? Id System
/dev/sda1?? *????? 0+??? 636???? 637-?? 5116671?? 83 Linux
/dev/sda2??????? 637???? 890???? 254??? 2040255?? 82 Linux swap / Solaris
/dev/sda3??????? 891??? 1527???? 637??? 5116702+ 83 Linux
/dev/sda4?????? 1528??? 2743??? 1216??? 9767520??? 5 Extended
/dev/sda5?????? 1528+?? 2135???? 608-?? 4883728+ 83 Linux
/dev/sda6?????? 2136+?? 2743???? 608-?? 4883728+ 83 Linux

二、parted 命令
parted?? 功能不错的分区工具;在Fedora 8中有带,可以自己安装上;调用方法简单,parted 默认是打开的设备是/dev/hda ,也可以自己指定;比如?? parted /dev/hda 或/dev/sda 等;退出的方法是 quit
输入parted命令后要等会儿才会出现下面的内容:
[root@localhost ~]# parted
GNU Parted 1.8.6
使用 /dev/sda
Welcome to GNU Parted! Type ’help’ to view a list of commands.
(parted)
在光标那里输入p回车出现下面内容:
Model: ATA Maxtor 5T040H4 (scsi)
Disk /dev/sda: 40.0GB
Sector size (logical/physical): 512B/512B
Partition Table: msdos
Number Start???? End???? S ize???? Type?? File system???? 标志
1????? 32.3kB?? 5240MB 5239MB?? 主分区??? ext3????????? 启动
2????? 5240MB 7329MB 2089MB 主分区??? linux-swap
3????? 7329MB 12.6GB 5240MB?? 主分区??? ext3
4????? 12.6GB 22.6GB?? 10.0GB 扩展分区
5????? 12.6GB 17.6GB?? 5001MB 逻辑分区?? ext3
6????? 17.6GB 22.6GB?? 5001MB 逻辑分区?? ext3
(parted)
在光标后面输入quit退出。

三、cfdisk -Ps命令 (注意P是大写)
cfdisk 也是一款不错的分区工具;在有些发行版中,此工具已经从util-linux包中剔除;cfdisk 简单易用是他的特点;
查看磁盘分区的用法?? cfdisk?? -Ps 磁盘设备名 只有一个硬盘也可以用 cfdisk -Ps
例1:[root@localhost ~]# cfdisk -Ps
Partition Table for /dev/sda
First???????? Last
# Type??????? Sector????? Sector?????? Offset???? Length????? Filesystem Type???????? (ID) Flag
-- -------?? ----------- -----------??? ------?? ----------- --------------------????? -------
1 Primary?????????? 0???? 10233404???? 63????? 10233405???????? Linux (83)???????????? Boot
2 Primary??? 10233405??? 14313914????? 0?????? 4080510?????? Linux swap / So (82)??? None
3 Primary??? 14313915??? 24547319????? 0????? 10233405???????? Linux (83)???????????? None
4 Primary??? 24547320??? 44082359????? 0????? 19535040?????? Extended (05)?????????? None
5 Logical??? 24547320???? 34314839???? 63?????? 9767520??????? Linux (83)???????????? None
?
????? 四、也可以使用?? 应用程序>系统工具>磁盘使用分析器?? 来查看磁盘使用情况。

五、fdisk -l 命令
fdisk 是一款强大的磁盘操作工具,来自util-linux软件包,我们在这里只说他如何查看磁盘分区表及分区结构;通过-l 参数,能获得机器中所有的硬盘的分区情况;
[root@localhost ~]# fdisk -l
Disk /dev/sda: 40.0 GB, 40000000000 bytes
255 heads, 63 sectors/track, 4863 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x62a9f8d0
Device Boot????? Start???????? End????? Blocks?? Id System
/dev/sda1?? *?????????? 1???????? 637???? 5116671?? 83 Linux
/dev/sda2???????????? 638???????? 891???? 2040255?? 82 Linux swap / Solaris
/dev/sda3???????????? 892??????? 1528???? 5116702+ 83 Linux
/dev/sda4??????????? 1529??????? 2744???? 9767520??? 5 Extended
/dev/sda5??????????? 1529??????? 2136???? 4883728+ 83 Linux
/dev/sda6??????????? 2137??????? 2744???? 4883728+ 83 Linux
sda1 是MBR(主引导记录)所在的分区;sda2是交换分区;sda4是扩展分区,包括了sda5,sda6两个逻辑分区。系统划分分区的时候只能划分4个主分区(扩展分区也算主分区),我在上面分了3个主分区+1个Extended分区,5.6是逻辑分区。所以才会有sda1.2.3.4.5.6。如果你只划分了1个主分区+1个扩展分区,那么逻辑分区就从sda5开始了,sda1.2.5.6...

六、df -lh 命令
df
