tree - Cross-Platform tree cli written in Rust

tree is an open-source tree command-line application that recursively displays the directory structure of a given path in a tree-like format, inspired by the Unix tree command. It is implemented in Rust and aims to provide a fast and efficient alternative with additional features, especially useful on platforms with no or limited tree cli features. Available for most platforms.

Features

• Display directory structure in a tree-like format
• Control the depth of recursion (-L or --level)
• Show full path (-f or --full-path)
• No indentation (-i or --no-indent)
• Display hidden files (-a or --all)
• Include specific files matching patterns (-P or --pattern)
• Display the size of each file (-s or --size)
• Display the total size of each directory (-H or --human-readable)
• Colorize output (-C or --color)
• Turn Colorization off (-n or --no-color)
• Use ASCII characters for tree display (-A or --ascii)
• List directories only (-d or --directories)
• Exclude specific files matching patterns (-I or --exclude)
• Send output to filename with -o flag
• Do not descend directories that contain more than # entries with --filelimit flag
• List directories first before files with dirsfirst flag
• Sort output by last modification time (-t)
• Reverse sort order (-r)
• Print last modification date (-D)
• Append file type indicators (/, *, etc.) (-F)
• Omit summary report (--noreport)
• Print permissions (-p)

Please feel to open PR requests in case interested in implementing some of the pending features.

Installation

Download Binaries

You can easily download binaries for different platforms from the Releases Page (Windows, MacOS, Linux).

• Download and unzip for your plaform
• If placing in $PATH, you can rename it to avoid confusing with any other tree binaries

Build from Source

If you have Rust and Cargo installed, you can build the project by running:

git clone https://github.com/peteretelej/tree.git
cd tree
cargo build --release

./target/release/tree -L 2 .  # or use --level=2
# copy tree binary to a PATH directory

The resulting binary will be located at ./target/release/tree.

Usage

Usage

./tree [FLAGS] [OPTIONS] [PATH]

For example:

# Using short flags
./tree -L 2 .
./tree -a -f -s .
./tree -P "*.txt" -I "*.log" .

# Using long flags
./tree --level=2 .
./tree --all --full-path --size .
./tree --pattern="*.txt" --exclude="*.log" .

Using as Rust Crate

use rust_tree::tree::{list_directory, options::TreeOptions};

fn main() {
    let path = ".";
    let options = TreeOptions {
        full_path: true,
        no_indent: true,
        ..Default::default()
    };
    list_directory(path, &options).unwrap();
}

Using the bytes_to_human_readable function to print human readable file sizes

use rust_tree::utils::bytes_to_human_readable;
use std::fs;

fn main() {
    let metadata = fs::metadata("my_file.txt").unwrap();
    let size = metadata.len();
    let size_str = bytes_to_human_readable(size);
    println!("File size: {}", size_str);
}
