If multiple disk drives are installed in the system and certain operations (such as repartitioning) need to be performed, the disk information needs to be obtained first. To obtain disk drive information, you need to view the list of installed disk drives. This list contains a lot of information about the installed drives.

Use the findmnt command to view the list of installed drives

The easiest way to view the installed disk drives is to use findmnt command:

findmnt

If you don’t like the tree layout information output by findmnt, let’s introduce some other methods below.

Use the cat command to view the list of installed drives

The cat command is used to read document content. Here, we use the cat command to read the contents of the file /proc/mounts:

cat /proc/mounts

The advantage of this method is that it can directly display the installed disk information.

Use the mount command to list Linux Mounted drive

The function of the mount command is described in the man manual as: The mount command is used to mount the file system (filesystem).

In addition to installing drives, you can also use it to obtain installed drive information, including viewing the list of installed drives.

The usage is very simple, just add the -l option after the mount command:

mount -l

In addition, if you want to view a certain file system type of drive, you can use the -t option, as follows:

mount -l -t 磁盘驱动器

For example, I want to view ext4 related information:

mount -l -t ext4

Use the df command to list the mounted drives in Linux

The df command is used to view the available disk space and can also be used to view the installed disk drives.

Use the df command to view the installed disk drive. You need to use 3 options, as shown in the following command:

df [选项] [目录或文件名]

Here:

• -a Get the file system ;
• -T Print file system type;
• -h Output information in human-readable form.

If you want to view the drive of a specific file system type, just add the -t option to the previous options.

For example, in the example we introduced the mount command above, to list the drives of the installed ext4 file system, you can use the following command:

df -a -T -h -t ext4
