This tutorial can be your solution. By the end of this article, you’ll be able to use the du command to view the size of directories and files, generate detailed disk usage reports, and sort the output of the du command. So, if you want to learn all about the du command, read on.

The Linux command line is a powerful interface that gives users full control over the system. The du command, also known as disk usage, is one of the most important Linux commands for analyzing disk usage within the system. The du command can be used to check the disk space usage of files and directories. In this tutorial, we will discuss the various aspects of the du command and its usage with examples.

Syntax of Du Command

The syntax of the du command is as follows:

du [OPTION]... [FILE]...

The du command has a few options that can be used to modify the output. The most common options are -a, -h, and -s. The -a option is used to display the disk usage of all files and directories. The -h option is used to display the output in a human-readable format. The -s option is used to display only the total disk usage of each argument.

Examples of Du Command

Now that we have discussed the syntax of the du command, let’s look at some examples. To get started, let’s use the du command without any options:

du

This will display the disk usage of all files and directories in the current working directory. The output will look something like this:

16   file124   file28    dir116   dir2

As you can see, the output displays the disk usage of each file and directory in the current working directory. Now, let’s use the -a option to display the disk usage of all files and directories:

du -a

This command will display the disk usage of all files and directories, including the hidden files and directories. The output will look something like this:

16   file124   file28    dir116   dir232   .file164   .dir1

As you can see, the output now includes the disk usage of all files and directories, including the hidden files and directories. Finally, let’s use the -s option to display the total disk usage of each argument:

du -s *

This command will display the total disk usage of each argument. The output will look something like this:

24   file164   dir1

As you can see, the output now displays the total disk usage of each argument. This is useful when you need to know the total disk usage of a group of files or directories.

In this tutorial, we discussed the various aspects of the du command and its usage with examples. The du command is a powerful tool for analyzing disk usage within the system. The du command has a few options that can be used to modify the output. We looked at examples of how to use the du command with the -a, -h, and -s options. We hope this tutorial was helpful and that you now have a better understanding of how to use the du command.

Suggestions to Improve Coding Skill

To improve your coding skills when using the du command, you should practice using it in different scenarios. Try different combinations of options and see what kind of output you get. Doing this will help you become more familiar with the command and how it works. Additionally, you should read the man pages for the du command to get a better understanding of what each option does and how it affects the output.
