Use the Linux mount command to mount the file system

Detailed explanation of the usage of Linux mount command mount

Linux is a widely used operating system with strong flexibility and scalability. Mounting is one of the commonly used operations in Linux. It can associate external storage devices or network shared directories with file systems to achieve access to these resources.

The mount command is the standard command in Linux for mounting file systems. The basic usage syntax is as follows:

mount [-l][-t 类型] [-o 选项] [-n] [-r] [-w] [-u] [-f] [-h] [-V] [--help] [--version] 设备 文件夹

The common options of the mount command are introduced in detail below:

1. -l: Display the list of mounted file systems.
2. -t Type: Specifies the type of mounted file system. Common file system types include ext4, ntfs, vfat, etc.
3. -o options: Specify additional options for mounting. Commonly used options include ro (read-only), rw (read-write), exec (allow execution), noexec (disable execution), noatime (do not update the access time of the file), etc.
4. -n: Cancel access to the /etc/fstab file. When mounting, Linux will look for the mount point defined in the /etc/fstab file and mount it automatically. The -n option can cancel automatic mounting.
5. -r: Mount the file system in read-only mode.
6. -w: Mount the file system in read-write mode.
7. -u: Uninstall the previously mounted device.

Example: Mount /dev/sdb1 to the /mnt directory, the file system is ext4, and it is mounted in read-write mode.

mount -t ext4 /dev/sdb1 /mnt

In actual use, the mount command can also be used in combination with other commands to implement more complex mounting operations. Some common examples are listed below.

1. Mount the network shared directory:

   mount -t cifs //10.0.0.1/share /mnt -o username=user,password=pass

   Among them, //10.0.0.1/share is the address of the network shared directory, /mnt is the local mount point, username=user,password=pass is the username and password of the shared directory.

2. Mount the ISO image file:

   mount -t iso9660 -o loop /path/to/iso /mnt

   Among them, /path/to/iso is the path of the ISO image file, / mnt is the local mount point.

3. Mount the Windows partition:

   mount -t ntfs-3g /dev/sda1 /mnt

   Among them, /dev/sda1 is the device name of the Windows partition, /mnt is the local mount point.

4. Mount a mobile device (such as a USB flash drive):

   mount -t vfat /dev/sdb1 /mnt

   Where, /dev/sdb1 is the device name of the mobile device,/mnt is the local mount point.

It should be noted that the mounting operation requires root privileges or the sudo command.

Summary:
The mount command is an important command in Linux for mounting a file system. This command can be used to access external storage devices or network shared directories.
