How to check the memory being used in Linux?

Hi Faisikhan,

In order to check the memory occupied by all the directories & files in one parent directory, you can use the below command:

du -all

For example, if you are in a parent directory like /etc, then using the above command will give us the space occupied by each file & directory in KBs & MBs.

Well, there can be possibilities that there are multiple directories and files in a single directory. So, if you want to check the space occupied by each directory in terms of depth levels, you will have to use the below command:

du -ah –max-depth=1

Now, you can increase the depth level like 2,3 etc.

I hope this helps you!

Hi Faisikhan,

Yes, the command used for checking the memory space occupied by all the directories and files is:

du -all

But if you want to view a summarized and in a human readable form, then you can use the below command:

du -sh or du -ah

Where h means "Human Readability", with the help of which you can get your answer in exact figures and words.

Hi linuxchunkers,

Thanks for your help. But I did not understand the word "h", what is its importance? And one more thing, how can I check the size of a single file or directory?

Is there also any available solution for that?

Thanks,

Dear Faisikhan,

With the help of "h", we will get the size or memory of the files and directory in readable form, I mean which can be understood by a human being easily. Let me explain you this via an example. You can feel the difference now:
