dutree is a free, open-source, fast command-line tool for analyzing disk usage, written in the Rust programming language. It was created by combining durep (disk usage reporter) and tree (list directory content in tree-like format) command-line tools. As a result, dutree reports disk usage in a tree-like structure.

dutree displays output with colors based on the settings defined in the GNU LS_COLORS environment variable. This variable allows you to customize file colors according to their extension, permissions, and type.

dutree Features:

• Displays the file system tree.
• Supports aggregation of small files.
• Allows comparison between different directories.
• Offers exclusion of specific files or directories.

How to Install dutree in Linux Systems

To install dutree on Linux systems, you must first have the Rust programming language installed. If it's not already installed, you can use the following curl command to install it:

<code>$ sudo curl https://sh.rustup.rs -sSf | sh</code>

Once Rust is installed, run the following command to install dutree from its GitHub repository:

<code>$ cargo install --git https://github.com/nachoparker/dutree.git</code>

After installation, dutree will use color settings based on the LS_COLORS environment variable, similar to how ls --color works.

<code>$ ls --color</code>

The simplest way to run dutree is without any arguments, which will display a filesystem tree.

<code>$ dutree</code>

To show real disk usage instead of file size, use the -u flag.

<code>$ dutree -u </code>

Show Directories in Depth

You can limit displayed directories to a certain depth (default 1) using the -d flag. For example, the command below shows directories up to a depth of 3, starting from the current working directory.

For instance, if the current directory is (~/), this will display the size of ~/*/*/* as shown in the screenshot.

<code>$ dutree -d 3</code>

Exclude Files or Directories in Output

To exclude a file or directory that matches a given name, use the -x flag.

<code>$ dutree -x CentOS-7.0-1406-x86_64-DVD.iso </code>

You can skip directories and get a quick local overview using the -f option, like this:

<code>$ dutree -f</code>

Use the -s flag to generate a full summary/overview:

<code>$ dutree -s</code>

Aggregate Small Files

It’s possible to aggregate files smaller than a specified size; the default is 1M.

<code>$ dutree -a </code>

Exclude Hidden Files

Use the -H option to hide hidden files from the output.

<code>$ dutree -H</code>

The -b flag prints sizes in bytes instead of kilobytes (the default).

<code>$ dutree -b</code>

To disable colors and display only ASCII characters, use the -A flag:

<code>$ dutree -A</code>

You can view the help message for dutree with the -h option:

<code><strong>$ dutree -h</strong>

Usage: dutree [options]  [..]

Options:
    -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</code>
