Linux Command Line Check Physical Disk Size

I am going to show you how to get the physical disk size for every disk in your system.

First, open a shell so you can access the command line (CLI). If you are on a server, you should already be there, unless you installed a GUI.

With the CLI ready, there two great commands you can use. They are:

df -HT

fdisk -l | grep Disk

Use either or both of those commands to get the disk sizes. If you get a “permission denied” message, just put sudo front of the command.

I hope that helps!
