As a newbie, one of the many things you should master in Linux is identifying the devices attached to your system. It could be your computer’s hard disk, an external hard drive, or removable media such as a USB drive or an SD memory card.
Using USB drives for file transfer is super common these days, and for those (new Linux users) who prefer using the command line, learning how to identify a USB device name is really important, especially when you need to format it.
Once you attach a device to your system, like a USB, it’s usually auto-mounted to a directory, normally under /media/username/device-label. From there, you can access its files just like any other folder. However, this isn’t the case with a Linux server. In server environments, you typically need to manually mount a device and specify its mount point.
