How to Find Folder Space in Linux Easily

Here's an example that shows how to use find command to get directory utilized space in Linux. Many of a time during production support, or when crontab jobs failed, the reasons behind is space shortage of a directory.

Folder space


The find is handy you can use to get utilized space of a directory. That helps you to delete unnecessary files (that actually make some space).


Linux find command


Here's the find command that I have used in our project. You will find here the detailed explanation of this command and how to use it.


find /home/srini -xdev -ls | sort +6rn | head -20


Part#1: Directory path


In the first part,  after the find you need to give the directory's path for which folder you are going to find space.


Part#2: Option -xdev


The second part is -xdev, which gives the space usage of all the subdirectories.


Part#3: Option -ls


The next part is the -ls option that provides a sorted list of all the subdirectories. 

Part#4: Sort command


Then, the sort command sorts based on the value +6rn.


Sort options


-n Sort numerically (10 will sort after 2), ignore blanks and tabs 
-r Reverse the order of sort 
-f Sort upper- and lowercase together 
+x Ignore first x fields when sorting


Part#5: Option +xrn


The value +6 states to ignore 6 columns in the sort. The option +rn sorts in descending order of memory.


Sort command


Part#6: Option head -20


The head -20 gets the top 20 rows of directories details.

The command you can use to find the folders which takes more space.

Tip#1 I have gone through the best books and Udemy courses. I am giving here for your reference. Here is the book on Bash scripting and Udemy course is Bash Mastery helpful to know more.
