Shell Scripting (Bash + Zsh)

A small, focused repository to help you learn shell usage + shell scripting by actually doing it.

Big projects can be powerful, but they can also get overwhelming fast. This repo stays intentionally simple so you can:

• follow along without burnout,
• read scripts that are easy to understand,
• spot mistakes/weaknesses,
• fix them (or improve them),
• and learn faster by interacting with real material.

What this project is about

This repo is a learning + practice space for:

• Bash scripting (common on Linux servers and many environments)
• Zsh usage/scripting (popular for interactive terminals)

You can follow along on:

• Kali Linux (VirtualBox) what I’m using
• any Linux distro
• macOS (Zsh is common)
• WSL (Windows Subsystem for Linux) on Windows

As long as you have a working shell (Bash or Zsh) and a terminal, you’re good.

Terms

• Shell: the program that reads your commands and runs them (e.g., bash, zsh).
• Script: a file (usually .sh) containing commands that run in order.
• Repo: repository (a project folder tracked by Git/GitHub).
• PR: Pull Request (a proposed change you want merged into the repo).

---

What you’ll get here

• Simple scripts you can run locally
• A structured “learning path” format (intro → examples → practice)
• A place to experiment safely and build confidence
• A beginner-friendly project that still teaches real workflows

Getting started

1) Clone the repository

1. Click the Code button on GitHub
2. Copy the HTTPS URL
3. Clone it:

git clone https://github.com/UnExplainableFish52/shell.git
cd shell

---

2) Read the materials

If you’re using VS Code:

• Open the folder
• Click README.md (or any .md file)
• Use the Markdown Preview (usually: Ctrl+Shift+V)

---

3) Run scripts (Bash / Zsh)

Option A — run with Bash

bash path/to/script.sh

Option B — run with Zsh

zsh path/to/script.sh

Tip: Explicitly using bash or zsh avoids confusion about which shell is executing the script.

Want deeper notes + practice?

If you want textbook-style notes + practice questions, use these pages:

• Notes: https://lokii.tech/intro/notes/1.7-shell-scripting.html
• Practice: https://lokii.tech/intro/notes/1.8-shell-scripting-practice.html

If you can understand everything there, you’re already moving into intermediate/advanced territory.

A learning mindset (important)

Don’t just copy commands—explore. When you hit something new:

• Google it
• test it in your terminal
• break it safely
• fix it
• write down what you learned

That “curiosity loop” is how your foundation becomes strong fast.
