+# Command line basics
+
+TThis tutorial shows the developer the basics of using the command line. It should take about 20 minutes to complete.

+## What is a Command Line Interface (CLI)?
+
+A Command Line Interface (CLI) is a text-based way to interact with your computer.
+Instead of clicking icons or buttons, you type commands into a terminal. Some examples
+of terminals include:
+
+-   **Bash** (Bourne Again SHell): Common on macOS and Linux systems.
+-   **cmd.exe**: The traditional command prompt on Windows.
+
+## How does it work?
+
+Users type commands into a CLI shell (e.g., Bash, cmd), which interprets and executes them:
+
+**Shell Role:** Acts as an intermediary between the user and the operating system<br>
+**Command Process:**
+The shell parses the command, identifying the action, options, and arguments. It locates the command in the system’s PATH and executes it. The system returns output (e.g., data, error messages) to the CLI.
+
+## Prerequisites
+
+-   A computer with a shell (macOS / Linux / Windows).
+-   A text editor you can run from the terminal (nano, vi, notepad, code, etc.).
+
+## Interacting with your command line
+
+Before using the command line, it's helpful to know which operating system and shell you are running. Different systems have slightly different commands; the examples below are grouped by platform so you can copy the commands that match your environment.
+
+````{tabs}
+```{tab} macOS / Linux
+```bash
+# Show OS/version information
+uname -a
+
+# Print working directory and list files
+pwd
+ls -la
+
+# Move around the filesystem
+cd /tmp
+cd ~
+cd ..
+
+# Create a directory and an empty file
+mkdir -p myproject
+touch myproject/hello.txt
+
+# Edit the file (simple editor)
+nano myproject/hello.txt
+# What to put in the file
+# Hello from the command line!
+
+# Print file contents
+cat myproject/hello.txt
+
+# Search inside the file
+grep "Hello" myproject/hello.txt
+
+# Show a CLI's help message (mycli here refers to any command line program e.g git, python, etc.)
+mycli --help
+python -m mycli --help
+````
+
+````
+
+```{tab} Windows (cmd.exe)
+```bat
+REM Show OS/version information
+ver
+
+REM Current directory and list files
+echo %CD%
+dir
+
+REM Move around
+cd /d C:\Temp
+cd /d %USERPROFILE%
+cd ..
+
+REM Create directory and file
+mkdir myproject
+type nul > myproject\hello.txt
+
+REM Edit with notepad
+notepad myproject\hello.txt
+
+REM Print file contents
+type myproject\hello.txt
+
+REM Search for Hello (findstr)
+findstr "Hello" myproject\hello.txt
+
+REM Show help for a CLI (mycli here refers to any command line program e.g git, python, etc.)
+mycli --help
+python -m mycli --help
+````
+
+```
+
+```
+
+## Short explanations (why these commands matter)
+
+-   Operating system information helps you choose the right commands and troubleshoot issues.
+-   Directories (folders) contain files and other directories. Paths can be absolute (start at the filesystem root) or relative (start from your current directory).
+-   Moving around with `cd` changes your working directory; many commands operate relative to it.
+-   Creating and editing small files is how you try things quickly from the terminal without opening a full IDE.
+-   Grep-style searching is essential for finding text in logs, configs, or code.
+-   Most CLIs expose `--help` (or `-h`) which documents commands, options, and usage.
+
+## Quick reference (cheat sheet)
+
+macOS / Linux
+
+```bash
+pwd             # print working directory
+ls -la          # list files
+cd <dir>        # change directory
+mkdir -p <dir>  # make directory
+touch <file>    # create empty file
+nano <file>     # edit
+cat <file>      # print contents
+grep <pat> <f>  # search
+mycli --help    # CLI help (mycli here refers to any command line program e.g git, python, etc.)
+```
+
+Windows (cmd.exe)
+
+```bat
+echo %CD%
+dir
+cd /d <dir>
+mkdir <dir>
+type nul > <file>
+notepad <file>
+type <file>
+findstr <pat> <file>
+mycli --help
+```
+
+## Conclusion
+
+Congratulations! You've completed the command line basics tutorial.
+You now have the foundational skills to navigate and interact with your computer using the command line. And you are ready to explore Click-based CLIs and build your own!
