Master Linux Disk Usage Visualization with Dutree: Install, Run, and Advanced Options

Dutree is a command‑line utility that visualizes directory structures and file sizes as a tree, helping users quickly identify large directories and manage disk space on Linux systems.

Dutree Overview

Dutree sorts files and directories by size and displays them in an intuitive tree diagram, making it easy to locate space‑hungry locations.

Installation

On most Linux distributions, install Dutree via the package manager. For Ubuntu/Debian:

sudo apt-get update
sudo apt-get install dutree

Other distributions can use their respective package managers.

Basic Usage

Run the tool in a terminal with the dutree command. It scans the current directory and its sub‑directories, then prints a tree with size information. dutree Example output:

/home/user
├── Documents       15.5 GB
│   ├── Work       8.2 GB
│   ├── Projects   5.3 GB
│   └── Reports    2.0 GB
├── Downloads      20.1 GB
├── Pictures       10.2 GB
└── Videos         30.5 GB

Total: 76.3 GB

Scanning a Specific Directory

Specify a path to analyze, e.g., the /home directory: dutree /home Result shows the size breakdown for /home and its subfolders.

Limiting Tree Depth

Use the -d option to restrict the displayed depth. To show only the first two levels: dutree -d 2 Output displays top‑level directories with their total sizes and the immediate sub‑directories.

Additional Features

Exclude Files or Directories

Exclude paths from the scan with --exclude:

# Exclude all .git directories
dutree --exclude .git

Display Sizes in Different Units

Choose units such as MB, GB, etc., using --unit:

# Show sizes in megabytes
dutree --unit MB

Export Results to a File

Redirect output to a file for later analysis:

# Save output to dutree_output.txt
dutree > dutree_output.txt

Show Hidden Files

Include hidden files in the report with the --all flag:

# Include hidden files
dutree --all

Interactive Mode

Enter an interactive view where arrow keys navigate the tree and sorting can be changed on the fly:

# Start interactive mode
dutree --interactive

Conclusion

By installing and using Dutree, Linux users gain a powerful way to visualize and manage filesystem disk usage, which can improve system performance and stability.
