Master the CLI Like a Programming Language

Check out Dev Resources, a free collection of over 1000+ developer tools and tutorials.

🧠 What If Your Terminal Was a Language?

We treat Bash or Zsh as a tool to run other tools, but never as a craft. What if we told you:

The shell is a full programming environment.
And mastering it is your realest dev power-up.

This article will show you how to:

• Stop copy-pasting random shell commands
• Use the terminal like a language, not a cheat sheet
• Build mini programs in your shell with intention
• Speed up your workflow across all stacks

💡 The Mindset Shift: From Command User to Shell Developer

Most developers use the terminal reactively:

“I found this command on StackOverflow, hope it works…”

But power users treat it like this:

“This shell pipeline is my custom compiler.”

🧠 Language Parallels:

🛠️ Part 1: Build a Shell Toolkit (Like a Dev Environment)

Just like you have IDE extensions, linters, and formatters, you can build a shell environment that thinks for you.

🔧 Tools to Install

• fd: find on steroids
• bat: Pretty cat
• fzf: Fuzzy everything
• rg (ripgrep): Super-fast grep
• tldr: Simplified man pages
• exa: Modern ls
• gh: GitHub CLI

⚡ Part 2: Write Shell “Functions” Like Real Code

Instead of rewriting commands 100 times:

backup_code() {
  tar -czf "backup-$(date +%s).tar.gz" ./src
}

Now you can just run:

backup_code

✅ Reusability
✅ Documentation (in your .bashrc)
✅ Mini-language fluency

🧪 Part 3: Create Language-Like Toolchains in Shell

Think of the CLI like function pipelines:

cat logs.txt | grep ERROR | sort | uniq -c | sort -nr

This is:

• Data ingestion (cat)
• Filtering (grep)
• Transforming (sort)
• Reducing (uniq, sort -nr)

Just like you'd do in a functional language — but in seconds.

🔍 Part 4: Make Your Shell Self-Documenting

You already document Python and JS code — why not your CLI?

✅ Example:

# ~/.bash_aliases

# Recursively find large files over 100MB
find_large() {
  find . -type f -size +100M -exec ls -lh {} \; | awk '{ print $9 ": " $5 }'
}

This is now:

• Searchable
• Composable
• Shareable

Create a whole library of functions, version it with Git, and back it up.

📦 Part 5: Package Your Shell Tools for Others

Yes, you can actually package your CLI creations like a mini-library.

🧪 Tools:

• chezmoi: Manage dotfiles as code
• dotbot: Declarative setup scripts
• shfmt: Autoformatter for shell code

You can even publish your own:

curl -s https://yoursite.sh/install | bash

🧠 Shell Programming Power-Ups

🧰 Useful Shell Snippets (Ready to Steal)

📂 Search for a file in all git repos:

find ~/code -name ".git" -type d | while read d; do
  repo=$(dirname "$d")
  echo "Searching in $repo"
  grep -r "TODO" "$repo"
done

🌐 Download a webpage and extract all links:

curl -sL https://example.com | grep -Eo '(http|https)://[^"]+'

⌛ Profile command time:

time ls -lahR /

🧭 TL;DR

🤪 Dev Emoji Theater

🧙 “I don’t write scripts. I cast spells in Bash.”
⚔️ “Pipelines are my weapon of choice.”
🚀 “One alias to rule them all.”
🐚 “Shell scripting is just functional programming with landmines.”
🧠 “My terminal is smarter than your backend.”
📜 “My .bashrc is 400 lines and glorious.”
💡 “The shell isn’t legacy — it’s legendary.”

💬 Tired of Building for Likes Instead of Income?

I was too. So I started creating simple digital tools and kits that actually make money — without needing a big audience, fancy code, or endless hustle.

🔓 Premium Bundles for Devs. Who Want to Break Free

These are shortcuts to doing your own thing and making it pay:

• 🌍 I built a simple website for a local biz and got $500+ — No design skills. Just solved a real problem.

• 🚀 Launched a SaaS in 7 days — no code, no audience — It’s messy but it works.

• 🔌 Used public APIs to build tiny tools people paid $997 for — Took what was already out there and made it useful.

• 📦 $300 in 3 days from a simple resource vault — Just organized links + tools. That’s it.

• 📈 Ranked a local site without writing a single blog post — SEO doesn’t have to be hard if you do it differently.

🔧 Quick Kits (Take 1 Product That Actually Works for You)

These are personal wins turned into plug-and-play kits — short instruction guides:

• ⚡ $1K in a week using APIs I didn’t even build — Copy-paste logic, add polish, publish.

• 🔥 My $0 dev setup now earns $97+ daily — Took years to build. Now it runs quietly in the background.

• 💼 This SaaS starter kit sells itself for $499 — Turns out, people love skipping setup pain.

• 📚 I turned academic papers into real products — It’s all just buried gold if you know where to look.

• 💡 My dev portfolio became a $297 product — I just told my story and sold the assets I made along the way.
