Total used free shared buff/cache available To see your server's memory, first, log into the WHM interface with your root user information, then go to Home > Server Status > Server Information and then scroll down to 'Current Memory Usage' and you will see something like this for the server's output:

Sometimes you may notice your server reports very little 'Free Memory,' however, this may not mean that your server is actually low on memory. To help with this we wanted to provide some more general information. Method 3: Check free disk usage graphicallyĬhecking free disk space graphically is much easier in Ubuntu with the Disk Usage Analyzer tool.At cPanel, we sometimes get inquiries about how and where memory is being used. For other Linux distros, you can refer to its GitHub releases section. dust → An interesting alternative to the du command written in Rust, available for Arch Linux in the repositories.fdisk -l →Shows disk size along with disk partitioning information (may require sudo privileges).stat →Displays the size and other stats of a file/directory or a file system.ls -al →Lists the entire contents, along with their size, of a particular directory.du -s Provides the total disk space used by a particular file or directory.du -h → Shows disk usage in human-readable format for all directories and subdirectories.While df command is quite popular and should be enough for the use case, there are other alternatives that you can try including: Since they are under root, you don’t need to count their used disk space separately.Īnd, if you want to view the disk usage with more details like filesystem type and blocks, you can use the command: df -TĬheck Your Disk Usage Using ‘duf’ Terminal Tool Method 2: Using du, ls, and Other Commands With the loop devices, snap applications are sandboxed in their own virtual disk. Loops are virtual devices that allow normal files to be accessed as block devices.

You’ll see plenty of them while checking disk space in Ubuntu because of snap applications. udev: The udev filesystem is used for storing information related to devices (like USB, network card, CD ROM etc) plugged to your system.

You can ignore this virtual filesystem comfortably.

tmpfs: The tmpfs (temporary filesystem) used for keeping files in virtual memory.

If you have 2-3 big partitions (like root, home etc), you’ll have to make a calculation here. In my case, I have used 41% of the 232 GB of disk space under root. Root is mounted on /, EFI in /boot/EFI etc. You could identify which partition is used for what purpose from its mount point. In such cases, these partitions are reflected with a number at the end of the ‘disk name’, like /dev/sda1, /dev/nvme0n1p2 etc. Your Linux system might have several partitions on your disk for boot, EFI, root, swap, home etc. This is not a hard and fast rule but it gives you an indication to easily recognize the actual disk from the crowd. Your actual disks should normally be listed as one of the following: When you use the df command to check disk space, it will show a bunch of ‘file systems’ with their size, used space and free space. Method 1: Checking free disk space in Linux with df command (and understanding its output) With the information you gather, you can go about making some free space on Ubuntu.

Using alternative commands like du and dust.
