When troubleshooting any disk space problems on a server or just trying to find the largest directories, the du
command is essential!
You can use the du
command which estimates the directory space usage.
For example, let’s say that we want to check the size of the directories located in the /home
directory. To do that let’s first cd
into the /home
folder:
- cd /home/
And then run the du
command:
- du -h --max-depth=1
[secondary_label Output]
16K ./demo
5.0G ./bobby
28K ./sammy
1.8G ./dev
7.1G .
I like running the du
command with the --max-depth=1
argument which only shows the size of the folders located inside the current directory and not the subfolders.
As you can see from the output the size is not sorted by size, here is how to do that!

What you could usually do in order to sort values in Linux is to use the sort
command.
However, if you pipe the output of the du -h
command directly into sort, it will not take into consideration the human-readable size format.
Lukily sort
comes with a -h
argument as well which would take the human-readable format into consideration and will compare the human-readable numbers.
So the full command would look like this:
- du -h --max-depth=1 | sort -h
For more information you can take a look at the official documentation here:
