如何在Linux中查看分卷信息

在Linux中，你可以使用多种命令来查看分卷信息。以下是一些常用的命令：

1. lsblk

lsblk（List Block Devices）命令可以列出所有可用的块设备及其挂载点。它会显示分区的层次结构。

lsblk

输出示例：

NAME   MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
sda      8:0    0   100G  0 disk 
├─sda1   8:1    0   50G  0 part /
├─sda2   8:2    0   50G  0 part [SWAP]
sr0     11:0    1  1024M  0 rom  

2. fdisk

fdisk命令可以用来查看和管理磁盘分区表。

sudo fdisk -l

输出示例：

Disk /dev/sda: 100 GiB, 107374182400 bytes, 209715200 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0x00000000

Device     Boot Start       End   Sectors Size Id Type
/dev/sda1  *       2048  10485759 10465312  5G 83 Linux
/dev/sda2       10485760 209715199 199229440  95 Extended
/dev/sda5       10485760  20971519   10485760  5G 82 Linux swap / Solaris

3. parted

parted命令也可以用来查看和管理磁盘分区。

sudo parted -l

输出示例：

Model: ATA ST31000528AS (scsi)
Disk /dev/sda: 100GB
Sector size (logical/physical): 512B/512B
Partition Table: msdos
Disk Flags: 

Number  Start   End     Size    File system  Name  Flags
 1      1049kB  51.0GB  50.9GB  ext4
 2      51.0GB  100GB   49.0GB  extended
 5      51.0GB  100GB   49.0GB  linux-swap(v1)

4. df

df命令可以显示文件系统的磁盘空间使用情况。

df -h

输出示例：

Filesystem Size Used Avail Use% Mounted on
udev            3.9G     0  3.9G   0% /dev
tmpfs           798M  9.6M  788M   2% /run

5. blkid

blkid命令可以显示块设备的UUID和文件系统类型。

sudo blkid

输出示例：

/dev/sda1: UUID="12345678-1234-1234-1234-123456789abc" TYPE="ext4"
