Starting Nano and opening a file

To get started with the Nano editor, open your terminal and navigate to the directory where the file you want to edit is located. To open or create a new file, enter the command: nano 50_Cars

Basic functions of the Nano editor

In the Nano editor you have various options you can use. At the bottom of the window, you will see a list of keyboard shortcuts for basic functions like saving and quitting. Note that you cannot work with the mouse here; all actions are controlled via the keyboard.

Entering and saving text

You can now enter text directly in the editor or edit values. For example: "This is my first Nano test". To save your changes, press Ctrl + O, after which you will be asked for a file name. Nano will suggest the already existing file name, which you can confirm by pressing Enter.

If you have added multiple lines, you will see a message indicating how many lines have been saved. If you are satisfied with the changes, you can exit the editor by pressing Ctrl + X.

Searching within the file

When working with larger files and wanting to search for a specific term, you can use the search function in the Nano editor. Press Ctrl + W, enter the word you want to search for, and press Enter again. Nano will take you to the first occurrence.

If you want to search for the word at another location, you can use Ctrl + B to show the next occurrence. This allows you to quickly navigate through the file and find what you're looking for.

Searching and replacing

One very helpful feature of Nano is the ability to search and replace. For example, if you want to replace the word "my" with "your", press Ctrl + W, then Ctrl + R. Now enter the word you want to replace, confirm with Enter, and then enter the new word.

After entering, Nano gives you the option to confirm each match one by one or to replace all occurrences at once. If you want to make multiple replacements, confirm them with "Y" for Yes or "A" for All.

Using help

If you ever feel stuck, the Nano editor offers an integrated help function. Press Ctrl + G to call up the help menu. Here you can scroll through various functions and commands to learn more about the capabilities of the editor.
