How to View Disk Space in Ubuntu

The transition from the Windows GUI to the Ubuntu terminal environment can be a daunting one. Nothing is familiar anymore, and even the simplest tasks are all of a sudden difficult. One such task is looking at your used or available disk space. Don’t worry; finding your disk space in Ubunutu is actually quite easy. Here is how to view your total disk space used in Ubuntu. 

How to view Total Disk Space Used in Ubuntu

To get the total disk space used in Ubuntu, we will use two commands. The first command will give us our filesystem. We will then use that information to get our used and available space left. Our two commands will be fdisk and df.

Step 1: Find your Filesystem

First, let’s look up our filesystem. In your terminal type

fdisk -l

The terminal will spit out a bunch of stuff, but we are interested in the last bit. You will get a list of “Devices” the one with the largest “Size” will be the one we are interested in. In our example, it’s “/dev/vda1

Device      Start       End   Sectors  Size Type
/dev/vda1  227328 167772126 167544799 79.9G Linux filesystem
/dev/vda14   2048     10239      8192    4M BIOS boot
/dev/vda15  10240    227327    217088  106M Microsoft basic data

Step 2: Check Used and Available Space

Next, we will look up our used and available space. In your terminal type 

df -h [FILE SYSTEM FROM STEP 1]

We will use the “Device” we found from the previous step in our second argument here. So for our example, we will enter df -h /dev/vda1

Your filesystem argument will likely be different.

Filesystem      Size  Used Avail Use% Mounted on
/dev/vda1        78G   46G   32G  59% /

Now we have our desired information. You can see the total size of your disk along with the currently used space, available space, and percentage used. 

Of course, now that we know our filesystem, we can skip the first step in the future. We can also use the df command without the filesystem argument. This will give us multiple filesystems. You can find the one you are interested in from the list and see the same information. 

df -h
Filesystem      Size  Used Avail Use% Mounted on
udev            1.9G     0  1.9G   0% /dev
tmpfs           395M  1.6M  393M   1% /run
/dev/vda1        78G   46G   32G  59% /
tmpfs           2.0G     0  2.0G   0% /dev/shm
tmpfs           5.0M     0  5.0M   0% /run/lock
tmpfs           2.0G     0  2.0G   0% /sys/fs/cgroup

That’s all there is to find your used or available disk space in Ubuntu. We hope you found this guide helpful and informative!
