fli-tool

Overview

fli-tool is a lightweight command-line utility that serves as an alternative to the traditional 'ls' command. Built with no_std Rust and Libc, it achieves a small binary size of approximately 18KB. Designed for efficiency, it provides basic directory listing functionality without relying on the Rust standard library, making it suitable for embedded or constrained environments. Note: This tool is not an AI chatbot; its category is listed as AI Chatbots for directory purposes.

Who Is This Tool Best For?

Developers seeking a minimal, fast, and memory-efficient ls replacement, especially in no_std or resource-limited contexts.

Answering the usual questions about fli

What is fli?

A very small directory-listing tool — an alternative to ls — written in Rust. The emphasis is on binary size and startup speed rather than on features.

Who is it for?

Developers who care about the size and speed of the utilities they run constantly, and anyone building minimal container images where every kilobyte counts.

What does it cost?

Our listing carries no price for it, so cost is undetermined. Check the source rather than assuming, though a tool of this kind is usually freely available.

Is it an AI tool?

Not in any meaningful sense. It appears in an AI-tools directory, but it is a filesystem utility, and nothing here claims otherwise.

Use cases

Replacing ls in a container image

A tiny static binary keeps an image small, which is the practical reason to choose it over the standard tool.

Listing directories quickly

Startup time is the whole point for something invoked constantly in a terminal session.

Studying minimal Rust

An 18KB tool that avoids the standard library is worth reading if you are learning how far that can be taken.

Pricing

fli is not given a price tier in our listing on ToolFlect. Cost is undetermined because no tier is published in our listing, and a utility of this kind is typically freely available from its repository. The meaningful comparison is against ls, which costs nothing. Details are in the repository. For current rates, the repository is the source.

Alternatives

  • ls — Already installed, and it does more.
  • exa or eza — A richer modern listing tool with colour and tree output.
  • fd — Finds files rather than listing them, and pairs well with this.

Our AI tools directory has the details on each.

Questions to settle first

Check it fits your platform

A minimal binary is built for particular targets. Confirm yours is one of them.

Expect fewer options than ls

The size comes from leaving things out. Scripts relying on flags may need adjusting.
