If you’re new to the world of command-line interfaces (CLI), you’re in the right place and you can find more information on the AllCommands.top. Whether you’re a developer, system administrator, or just curious about how to navigate your computer using text-based commands, this beginner’s guide will help you get started with two popular CLI tools: CMD (Windows Command Prompt) and Bash (Unix-like shell). What Is the Command Line?

The command line is a tool that allows you to interact with your computer by typing commands directly. Unlike graphical user interfaces (GUIs), which rely on icons and mouse clicks, the command line lets you perform tasks efficiently using text-based instructions.

CMD (Windows Command Prompt)

Basics:

1. Opening CMD: Press Win + R, type cmd, and hit Enter.
2. Navigating Directories:
   • cd: Change directory (e.g., cd Documents).
   • dir: List files and folders.
3. Creating and Deleting Files/Folders:
   • mkdir: Create a new directory.
   • del: Delete a file.
4. Running Programs:
   • Type the program name (e.g., notepad).

Tips:

• Use Tab for auto-completion.
• Ctrl + C stops a running command.
• Ctrl + V pastes text.

Bash (Unix-like Shell)

Basics:

1. Opening Bash:
   • On Linux/macOS: Open the terminal.
   • On Windows: Install Git Bash or use Windows Subsystem for Linux (WSL).
2. Commands:
   • Similar to CMD (e.g., ls, cd, mkdir).
   • Case-sensitive.

Advanced:

1. Pipes and Redirection:
   • |: Pipe output from one command to another.
   • >: Redirect output to a file.
2. Environment Variables:
   • $VAR_NAME: Access environment variables.
3. Scripting:
   • Write shell scripts (.sh files).

Tips:

• Use Ctrl + L to clear the screen.
• Learn keyboard shortcuts (e.g., Ctrl + A for start of line).

Practice Makes Perfect

1. Create a folder using CMD.
2. List files in that folder using Bash.
3. Run a program (e.g., notepad in CMD or nano in Bash).

Remember, mastering the command line takes practice. Start small, explore, and soon you’ll be navigating your system like a pro!
