Dutree – Command Line Disk Usage Analysis Tool on Linux

DUtree is a combination of Durep and Tree. Durep creates disk usage reports with graphs which allows us to identify which directories are using the most space. Although durep can produce text output similar to du, its real power is the ability to store reports in a file. Tree is directory displaying program that recursively list directory in tree like structure on Terminal. Tree is clean and simple program that you can use to build tree like structure for directories and file systems.This leads me to list down features of DUtree,

  • Fancy - Coloured output,
  • Hierarchical Display the file system,
  • User can aggregate small files,
  • User can exclude files or directories,
  • User can compare different directories,
  • Reliable & Fast.

DUTree is written in RUST programming Language, Rust is systems programming language that runs amazingly fast, prevents segfaults, and thread safe. Today, I will be showing you how to install DUTree on CentOS 7 and Ubuntu 16.04. Below tutorial starts from Installation on Git and RUST, if you already have completed this you can move to Dutree Installation. Please note, RUST Installation is must for this tutorial to run.

Git Installation

Ubuntu 16.04

$ sudo apt install git

CentOS 7

$ sudo yum install git

RUST Installation

Ubuntu 16.04

$ sudo apt install curl 

$ curl https://sh.rustup.rs -sSf | sh

Centos 7

$ curl https://sh.rustup.rs -sSf | sh

DUTree Installation

$ git clone https://github.com/nachoparker/dutree.git

Welcome to Rust! 

This will download and install the official compiler for the Rust programming 
language, and its package manager, Cargo. 
It will add the cargo, rustc, rustup and other commands to Cargo's bin directory, located at:   /home/administrator/.cargo/bin 
This path will then be added to your PATH environment variable by modifying the 
profile file located at:   /home/administrator/.profile 
You can uninstall at any time with rustup self uninstall and these changes will be reverted. 
Current installation options:    
  default host triple: x86_64-unknown-linux-gnu
  default toolchain: stable 
  modify PATH variable: yes 

1) Proceed with installation (default) 
2) Customize installation 
3) Cancel installation

Rust is installed now. Great! 

To get started you need Cargo's bin directory ($HOME/.cargo/bin) in your PATH 
environment variable. Next time you log in this will be done automatically. 
To configure your current shell run source $HOME/.cargo/env

Setting Source

The source command can be used to load any functions file into the current shell script or a command prompt,

$ source $HOME/.cargo/env

General Help option, shows list of options and what it performs,

$ dutree –-help 

Usage: dutree [options] <path> [<path>..] 
    -d, --depth [DEPTH] show directories up to depth N (def 1) 
    -a, --aggr [N[KMG]] aggregate smaller than N B/KiB/MiB/GiB (def 1M) 
    -s, --summary       equivalent to -da, or -d1 -a1M 
    -u, --usage         report real disk usage instead of file size 
    -b, --bytes         print sizes in bytes 
    -x, --exclude NAME  exclude matching files or directories 
    -H, --no-hidden     exclude hidden files 
    -A, --ascii         ASCII characters only, no colors 
    -h, --help          show help 
    -v, --version       print version number 

Below are all example using various options to show use of dutree,



The depth of a directory is the number of edges from the file/directory to the tree's root directory. A root directory will have a depth of 1. The height of a file is the number of edges on the longest path from the directory to a leaf.

You can look at first directory depth by,

$ dutree -d1 test/

or want to see more files in depth,

$ dutree -d2 test/

or see everything,

$ dutree test/


To have quick overview for specified directory use option -s.

$ dutree -s test/

you can also see file size in bytes using -b option,

$ dutree -b test/

if you want to see files excluding specific extension or file or directory name you can use -x option,

$ dutree -x dir1 test/

below you see that dir1 is excluded from tree,


You can aggregate files under a certain directory or specify certain file size for better visualization,

$ dutree -a 100b test/

Real Disk Usage

In below image you see, how to check real disk usage instead of file size. The file size of files is not equivalent to the disk usage, this are the real amount of disk blocks that are used. Small files generally takes more space than we assume because only one small file will be stored in one block.

$ dutree -u test/


You can compare any number of different folders,

ASCII characters

In below image you see, How to use dutree specifying directory path. If you are type of person who don’t care about trendy colors or have problems with block characters in your old terminal, you can get the output in good old plain ASCII characters.

$ dutree -A test/

Try using LS_COLOR variable for fancy colours for your environment and let us know your comments.
