What is mnt in linux

Last updated: April 1, 2026

Quick Answer: /mnt is a standard directory in Linux's filesystem hierarchy used as a temporary mount point for attaching storage devices and filesystems. It allows administrators to access external drives, network shares, and other storage volumes.

Key Facts

/mnt directory follows the Filesystem Hierarchy Standard (FHS) established by the Linux Foundation
It is used for manually mounting external storage devices, USB drives, and network shares
The mount command is used to attach filesystems to /mnt or its subdirectories
/mnt differs from /media, which is typically used for automatic mounting of removable media
Mounted filesystems accessed through /mnt become part of the main filesystem hierarchy, allowing normal file access

Understanding /mnt in Linux

In Linux operating systems, /mnt is a standard directory within the root filesystem hierarchy that serves as a mount point for temporary filesystem attachments. Mount points are directories where external storage devices, network shares, or other filesystems are integrated into the main filesystem tree. The /mnt directory specifically is designated by the Filesystem Hierarchy Standard (FHS) as the location for administrators to mount additional filesystems that are not part of the permanent system.

The Mount Process

When you want to access an external storage device in Linux, you must first mount it to a directory. This process makes the device's filesystem accessible through that directory path. For example, mounting a USB drive to /mnt/usb allows you to navigate to /mnt/usb and access the drive's contents as if they were part of your main filesystem. The mount command, used with root privileges, establishes this connection between the physical device and the directory.

/mnt vs /media

Linux includes two primary mounting directories: /mnt and /media. The /mnt directory is intended for manual, administrator-controlled mounting of devices and network shares. The /media directory, by contrast, is typically used by the system or desktop environment to automatically mount removable media like USB drives and external hard drives without user intervention. In modern Linux distributions, /media is often the primary location where automatically detected devices appear, while /mnt serves more specialized mounting needs.

Practical Uses

Common uses for /mnt include mounting external hard drives for backup or data transfer, accessing network-mounted filesystems (NFS shares), mounting ISO images, and providing temporary access to additional storage. System administrators frequently use /mnt to organize and manage multiple mounted devices. Creating subdirectories within /mnt, such as /mnt/backup or /mnt/external, helps organize different mounted devices logically and prevents confusion.
