How to limit output depth?

To limit the output depth when checking disk usage with the du command in a Linux environment, you can use the --max-depth option. This option allows you to specify how many levels of subdirectories you want to display in the output.

Syntax

The basic syntax for using --max-depth is:

du -h --max-depth=N /path/to/directory

Where N is the depth level you want to limit the output to.

Example Usage

Check Immediate Subdirectories: If you want to see the sizes of only the immediate subdirectories within a directory, set N to 1:
```
du -h --max-depth=1 ~/project
```
This command will display the sizes of the project directory and its immediate subdirectories, but not any deeper levels.
Check Two Levels Deep: If you want to see sizes for two levels of subdirectories, set N to 2:
```
du -h --max-depth=2 ~/project
```
This will show the sizes of the project directory, its immediate subdirectories, and their immediate subdirectories.

Example Output

For a directory structure like this:

project/
├── subdir1/
│   ├── file1.txt
│   └── file2.txt
├── subdir2/
│   └── subsubdir1/
│       └── file3.txt
└── file4.txt

Running du -h --max-depth=1 ~/project might produce output like:

4.0K    /home/labex/project/subdir1
8.0K    /home/labex/project/subdir2
12K     /home/labex/project

And running du -h --max-depth=2 ~/project would show sizes for subsubdir1 as well:

4.0K    /home/labex/project/subdir1
4.0K    /home/labex/project/subdir2/subsubdir1
8.0K    /home/labex/project/subdir2
12K     /home/labex/project

Summary

Using the --max-depth option with the du command is a powerful way to control the granularity of the output, making it easier to analyze disk usage without overwhelming detail.
