A mount point is a directory in a filesystem where a storage device (like a hard drive, USB drive, or virtual disk) is attached or "mounted." When a device is mounted at a mount point, its contents become accessible through that directory in the filesystem hierarchy.
Key Concepts:
-
Accessing Storage: Mount points allow users and applications to access the files and directories on a storage device as if they were part of the main filesystem. For example, if you mount a USB drive at
/mnt/usb, you can access its files by navigating to that directory. -
Filesystem Hierarchy: In Linux, the filesystem is organized in a single tree structure, starting from the root directory (
/). Mount points integrate additional storage devices into this structure. -
Temporary vs. Permanent Mount Points:
- Temporary Mount Points: Created during a session (e.g., using the
mountcommand) and typically removed when the system is rebooted. - Permanent Mount Points: Defined in the
/etc/fstabfile, allowing devices to be automatically mounted at boot time.
- Temporary Mount Points: Created during a session (e.g., using the
Example of Mounting:
To mount a device (e.g., a USB drive) at a mount point, you might use a command like:
sudo mount /dev/sdb1 /mnt/usbIn this example:
/dev/sdb1is the device identifier./mnt/usbis the mount point where the device's contents will be accessible.
Unmounting:
When you are done using the mounted device, you should unmount it to ensure all data is written and to safely remove the device:
sudo umount /mnt/usbFurther Learning:
