This article is about how to check the use of disks in the Ubuntu system, the editor thinks it is very practical, so I share it with you to learn. I hope you can get something after reading this article.

1. On the system, click the lower left corner of the desktop, as shown in the figure.

2. In the system, click the utility, as shown in the figure.

3. Click on disk usage, as shown in the figure.

4. Then you can see the use of the disk, that is, the middle disk is your computer's hard disk, as shown in the figure. The small print under the disk is the usage.

5. Or click the disk on the utility, as shown.

6. In the capacity, you can see the usage of the hard disk, as shown in the figure.

Here is the text version

View disk usage:

Df-h

The results are as follows:

The utilization rate of my previous / dev/vdb1 reached 100%, resulting in MongoDB being unable to write files and entering the fail state.

Let's start from the root directory /, look at the files or folders that take up a large amount of space step by step, and clean up the files that are not used.

Enter / directory:

Cd /

View the volume of each file and folder

Du-sh *

The results are as follows:

28K a.txt

28K a.txt.save

13M bin

96M boot

4.0K deploy.py

12K dev

12K docker

Then I usually start with the largest file and see if it can be deleted, over.

Delete the command, you must take the folder name, or you will delete it.

Rm-rf {file or folder name}

The above is how to check the disk usage in the Ubuntu system. The editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article. For more details, please follow the industry information channel.
