4 Ways to Find Plugged USB Device Name in Linux

For new Linux users, identifying connected devices is crucial, especially USB drives. This guide provides several command-line methods to determine a USB device's name, essential for tasks like formatting. While USB drives often auto-mount (e.g., /media/username/device-label), server environments usually require manual mounting, necessitating device name identification. Linux uses device files in /dev (e.g., /dev/sda, /dev/sda1 for partitions) to represent these devices.

ls /dev/sda*

Here are several command-line tools:

1. df -h: This command displays disk space usage, including mounted devices and their mount points.

df -h

2. lsblk: The lsblk (list block devices) command provides a comprehensive list of all block devices connected to your system.

lsblk

3. sudo fdisk -l: The fdisk utility displays the partition table for all block devices, including USB drives. Requires root privileges (sudo).

sudo fdisk -l

4. dmesg: This command shows kernel messages, including information about USB devices when they are plugged in. Look for recent entries related to USB device connection.
