Hello, WorldThis is officially the first post! How exciting!We all have spent a vast number of minutes, hours, years, etc. researching various topics in search of a solution to whatever problem we had come across at any given time.
We may find a solution and complete the project, and update its documentation; other times, we may jot down a note and store it some place safe (where did I place my notepad again…), or we may simply forget it and move onto whatever else needing attention. I am guilty of the latter, the latter latter, and on occation, the latter latter latter.
Prompt Fu provides a simple interface, the Markdown lanugage, to share my thoughts and work, and it is OPEN.
Given that open source has been such a huge catalyst in the world of technology and vastly helpul thorughout my career; Prompt Fu offers, for starters, my notes, blogs, wikis, projects, etc. as I continually develop throughout my career and life.
As I, and maybe someday others, share, the opportunity for you to contribute and share your thoughts is available and encouraged! Each blog and wiki should have a comments section found at the bottom of the page. Please, feel free to comment suggesting edits, start discussions, or to let me know the post helped you in your search.
Additionally, wiki posts have an ”improve this post” link which will take you directly to GitHub so you can fork, edit, and pull request to contribute.
With that said, more interesting posts are coming so be sure to check back soon; also be sure to check out the various wikis that include tech tips and command line fu that I have found useful in my everyday - Wiki.
In an attempt to leave you inpired, here are 10 quotes about technology that I thought had a certain je ne sais quoi.
Technology is a word that describes something that doesn’t work yet. — Douglas Adams
Just because something doesn’t do what you planned it to do doesn’t mean it’s useless. — Thomas Edison
One machine can do the work of fifty ordinary men. No machine can do the work of one extraordinary man. — Elbert Hubbard
Communications tools don’t get socially interesting until they get technologically boring. — Clay Shirky
Technology is the campfire around which we tell our stories. — Laurie Anderson
Hardware: the parts of a computer that can be kicked. — Jeff Pesis
Getting information off the Internet is like taking a drink from a fire hydrant. — Mitchell Kapor
Technology is unlocking the innate compassion we have for our fellow human beings.
— Bill Gates
Technology is nothing. What’s important is that you have a faith in people, that they’re basically good and smart, and if you give them tools, they’ll do wonderful things with them. — Steve Jobs
In open source, we feel strongly that to really do something well, you have to get a lot of people involved. — Linus Torvalds
What PromptFu Has Become (2026 Update)
This post was written in 2019 as the very first entry on the site. Since then, PromptFu has grown significantly — and the name has taken on new meaning.
When I started this site, “Prompt Fu” referred to the command line prompt — the blinking cursor that developers, sysadmins, and hackers stare at all day. The wiki is full of command-line cheat sheets for tools like grep, sed, bash, vim, and rsync — quick references I built up over years of Linux work.
Then AI happened.
In 2023 and beyond, “prompt” took on a new meaning: the text you feed to a large language model to get useful output. Suddenly, “Prompt Fu” described something bigger — the art of crafting prompts that work. Writing a good AI prompt has its own techniques, patterns, and hard-won wisdom, just like mastering awk or sed.
PromptFu now covers both:
- Command-line fu — terminal tools, shell tricks, and DevOps cheat sheets
- AI prompt fu — techniques for getting the most out of ChatGPT, Claude, GitHub Copilot, and other LLMs
What You’ll Find Here
Blog posts explore tools and techniques in depth:
- AI-Powered Command Line Tools Every Developer Should Know
- GitHub Copilot CLI Mastery Guide
- Prompt Engineering Guide for Developers
- What is Promptfoo? AI Prompt Testing Explained
Wiki cheat sheets are the quick-reference layer — the kind of page you keep open in a browser tab:
The Original Vision, Refined
The original mission — a place to collect and share hard-won technical knowledge — has not changed. The medium is still Markdown. The audience is still developers who live in the terminal and want practical, no-nonsense reference material.
What has changed is the subject matter. The most valuable command you can type in 2026 might not be a shell one-liner. It might be a prompt.
Welcome to PromptFu. Let’s master both arts. 🥋
