Show HN: Fst – Lightweight C utility for detailed directory statistics LGPL 3.0

2 Forgret 0 9/3/2025, 11:00:06 AM

Hi HN,

I’ve just released fst, a minimalistic C utility that provides comprehensive statistics about directories. It’s designed to be fast, with no dependencies, and is fully statically compilable.

Features:

Counts of files, directories, empty files/folders

Classifies binary, text, and script files

Displays min, max, and average file sizes

Identifies recent and oldest files

Lists executable files, symbolic and hard links

Supports human-readable sizes and recursive stats

Key Points:

Written in pure C, minimal dependencies, lightning fast

Works on both ARM and x86 architectures, fully statically compilable

Can run with no arguments (defaults to the current directory)

Licensed under LGPL 3.0

GitHub repository: https://github.com/Ferki-git-creator/fst-ferki

Submitted to GNU for review

I'm seeking feedback, ideas, and contributions from the community. The goal is to enhance usability, add more metrics, and possibly extend internationalization support in the future.

Any thoughts or suggestions would be highly appreciated!
