Using Nano

Nano is a simple, user-friendly text editor included with most Linux distributions. It’s ideal for quick file and configuration edits directly from the terminal.

💻 Opening Nano

1. Open a File in Nano:

   • To open a file (or create one if it doesn’t exist), use:

     nano [filename]

   • Example:

     nano myfile.txt

   • This opens myfile.txt for editing.

2. Open Nano Without a File:

   • If you want to open Nano without specifying a file, type:

     nano

   • This starts a blank session where you can start typing and later choose to save or discard the file.

ℹ️ Basic Nano Commands

Nano has a set of commands accessible via the keyboard. Here’s a rundown of the essentials:

1. Navigating in Nano:

   • Arrow Keys: Move up, down, left, or right within the file.

   • Page Up / Page Down: Quickly scroll up or down a page.

   • Ctrl + _ (underscore): Jump to a specific line and column by entering the line number.

2. Editing Text:

   • Insert Text: Type as you normally would.

   • Delete Text: Use the Backspace or Delete key to remove characters.

3. Cut, Copy, and Paste:

   • Cut Text: Use Ctrl + K to cut the current line. Repeat to cut multiple lines.

   • Copy Text: Use Alt + 6 to copy the current line. (Hold Alt and press 6.)

   • Paste Text: Use Ctrl + U to paste the text at the cursor’s location.

4. Search and Replace:

   • Search: Press Ctrl + W, type the search term, and press Enter. Nano will jump to the first match.

   • Find Next: Press Ctrl + W again and hit Enter without typing to jump to the next instance.

   • Replace: Use Ctrl + \ and follow the prompts to replace text.

Saving and Exiting

1. Save Changes:

   • Press Ctrl + O (letter O, for "output"), then hit Enter to confirm the filename.

   • Nano displays the filename at the bottom of the screen for verification.

2. Exit Nano:

   • Press Ctrl + X. If there are unsaved changes, Nano will prompt you to save before exiting. Type Y (Yes) or N (No), and press Enter.

ℹ️ Additional Nano Commands

• Show Help: Press Ctrl + G to access the help menu, which lists all available commands.

• Undo/Redo: Use Alt + U to undo and Alt + E to redo changes.

• Show Line Numbers: Start Nano with the -l option for line numbers:

  nano -l [filename]

⬅️ Example Workflow

1. Open a file for editing:

   nano example.txt

2. Edit the content by typing directly into the editor.

3. To save, press Ctrl + O, confirm the filename with Enter.

4. To exit, press Ctrl + X.

ℹ️ Common Issues

• Arrow Keys Don’t Work: Ensure Num Lock is off or try using Ctrl key combinations if you’re in a minimal terminal.

• Permission Denied: If editing a file that requires root permissions, use sudo before the command:

  sudo nano /etc/hosts

Nano is mainly used for quick edits, and it’s efficient and simple to learn. You'll find yourself making quick changes to the .sh files for the bot.
