In plain words
McFly is a command-line tool that replaces standard Bash history search with machine learning. Written in Rust, it uses a neural network to intelligently rank and surface the most relevant previous commands based on user context and patterns. It's designed for developers and terminal users who want faster access to frequently used or contextually appropriate commands from their history.

Warp, a Rust-based terminal2022 · warp.dev · ▲946Hi HN community, I’m Zach, founder and CEO of Warp, and am excited to show you Warp, a fast Rust-based terminal that’s easy to use and built for teams. As of today, Warp is in public beta and any Mac user can download it. It works with bash, zsh, and fish. The terminal’s teletype-like interface has made it hard for the CLI to thrive. After 20 years of programming, I still find it hard to copy a command’s output; I always forget how to use `tar`; and I always have to relearn how to move my cursor. To fix fundamental accessibility issues, I believe we need to start innovating on the terminal,…
Parqeye – A CLI tool to visualize and inspect Parquet filesNov 2025 · github.com · ▲167I built a Rust-based CLI/terminal UI for inspecting Parquet files—data, metadata, and row-group-level structure—right from the terminal. If someone sent me a Parquet file, I used to open DuckDB or Polars just to see what was inside. Now I can do it with one command. Repo: https://github.com/kaushiksrini/parqeye

HiSHtory: Your shell history in context, synced, and queryable2022 · github.com · ▲179hiSHtory is a better shell history. It stores your shell history in context (what directory you ran the command it, whether it succeeded or failed, how long it took, etc). This is all stored locally and end-to-end encrypted for syncing to to all your other computers. All of this is easily queryable via Control-R and via the hishtory CLI. This means from your laptop, you can easily find that complex bash pipeline you wrote on your server, and see the context in which you ran it.
