Mount points on Linux refer to the locations in the directory tree where a storage device or file system is attached or "mounted." When a device is mounted on a mount point, its contents become accessible as part of the file system hierarchy. Here are some important points to keep in mind when thinking about mount points on Linux:
1. Every mount point must have a unique location in the directory tree, and it cannot be a subdirectory of an existing mount point.
2. Mount points can be created manually using the `mount` command or automatically using tools like `fstab` or `autofs`.
3. Mount points can be used to access a variety of storage devices and file systems including hard drives, USB drives, network drives, and virtual file systems.
4. Mount points can be configured with different options, such as read-only access or user-specific permissions.
5. It’s important to unmount storage devices and file systems before physically disconnecting them to avoid data loss or corruption.
Understanding mount points is an important part of Linux system administration, especially for managing large or complex file systems. By properly configuring and managing mount points, you can ensure efficient and secure access to your data.

How do I find the mount point in Linux?
In Linux, a mount point is the location in the file system where a mounted file system or device is attached. It is essential to know the mount point of a file system or device in Linux to access its contents. Here are the steps to find the mount point on a Linux system:
1. Open the terminal: Launch the terminal on your Linux system, either by searching for it through the applications menu or using the keyboard shortcut "Ctrl + Alt + T."
2. Enter the command: Once you have opened the terminal, type the following command:
`df -h`
The `df` command shows you the disk space used and available on all mounted file systems, and the `-h` option formats the output in a human-readable format.
3. Look for the device or file system: Scroll through the output until you find the device or file system that you want to find the mount point for. The first column shows the device or file system’s name, and the last column shows the mount point.
4. Note down the mount point: Once you have found the device or file system’s mount point, note it down so that you can easily navigate to it later.
That’s it! You now know how to find the mount point of a device or file system on a Linux system using the terminal.
What does Linux do with existing files in a mount point?
When a file system is mounted in a specific directory, that directory becomes a "mount point" for the file system. When files are accessed or created in that directory, Linux directs these operations to the file system that is mounted on the directory.
If an existing file exists in the directory that is used as a mount point, it is hidden or obscured by the file system that is mounted on the directory. Essentially, the file system that is mounted "covers up" the existing files in the directory.
However, it’s important to note that the original files are not deleted or removed. They are simply inaccessible while the other file system is mounted on the directory. Once the file system is unmounted from the directory, the original files will become visible and accessible again.
It’s also worth noting that there may be exceptions or variations to this behavior depending on the specific file system and type of mount point being used. However, in general, this is how Linux handles existing files in a mount point.
How do I create a mount point in Linux?
To create a mount point in Linux, you can follow these steps:
1. Open the terminal on your Linux machine.
2. Log in as a superuser or switch to the root user by using the “su” command.
3. Choose an appropriate location for your mount point. Conventionally, it should be under the “/mnt” directory, but you can create the mount point directory anywhere you desire.
4. Create a new directory for the mount point using the “mkdir” command. For instance, you can name your mount point “my_mount_point”:
"`
mkdir /mnt/my_mount_point
"`
5. Once the mount point directory is created, you can mount the desired device or partition to it. For this, you need to know the device name (e.g., /dev/sda1) or its file system type (e.g., ext4).
6. Use the “mount” command like this to mount a device or partition (replace “/dev/sda1” and “ext4” with your device name and file system type):
"`
mount -t ext4 /dev/sda1 /mnt/my_mount_point
"`
7. Once the device is mounted to the mount point, you can access its content as if they are present in the mount point directory.
Note that you should have appropriate permissions to create and access the mount point and mount the device. Mounting a device also requires root or sudo privileges.
What is a mount point?
In the context of computing, a mount point is a directory on a file system where an additional file system is mounted. The mounted file system can be a hard disk partition, a USB storage device, or a network file system. The operating system uses mount points to organize and access different file systems in a hierarchical manner.
Here are a few key points to understand about mount points:
1. Mount points are used to attach additional file systems to the main file system of an operating system.
2. Mount points are created by the system administrator or by the operating system during installation.
3. The mount command is used to attach a file system to a mount point.
4. When a file system is mounted, the files and directories in the mounted file system become accessible under the mount point directory.
5. Mount points can be accessed like any other directory in the file system hierarchy.
6. Unmounting a file system removes the link between the file system and the mount point, making the files and directories in the mounted file system inaccessible.
7. Mount points can be managed using various system utilities, such as mount, umount, fstab, and df.
What is mount in Linux with example?
In Linux, "mount" is a command that is used to attach a file system to a specific point in the directory tree, thereby allowing access to the contents of the file system. Here is an example of using the mount command:
1. Suppose you have a hard drive that you want to mount. First, you need to know the name of the device file for the hard drive. You can do this by running the command "fdisk -l" (as root) and looking for the name of the hard drive (e.g. /dev/sdb1).
2. Next, you need to create a mount point in your file system. This is the directory where the contents of the hard drive will be accessible. You can create a new directory (e.g. /mnt/hard_drive) or use an existing one.
3. Finally, you can mount the hard drive to the mount point using the mount command. For example, if the hard drive is /dev/sdb1 and the mount point is /mnt/hard_drive, you can run the following command: "mount /dev/sdb1 /mnt/hard_drive".
After running this command, you should be able to access the contents of the hard drive by navigating to the mount point (/mnt/hard_drive) in your file system. It is important to note that you need to have root privileges to run the mount command or else you need to use "sudo" before the mount command.
