 Step-by-Step Guide to Accessing the Command Line and Opening the Text Editor

This is aimed to provide a detailed step-by-step guide on accessing the command line interface
and opening the text editor in Ubuntu Linux. The guide outlines the actions taken to navigate the
command line and the command issued to open the text editor

1. Accessing the Command Line

a. The command line interface was accessed by launching the Terminal application from the
Ubuntu Linux GUI.

b. Upon launching the Terminal, a new terminal window appeared, providing the command line
environment.

2. Navigating to the Default Editor

a. The default text editor, Nano, was accessed by typing the command "nano" in the terminal
window.

b. Pressing the Enter key initiated the opening of Nano, displaying a blank document or an
existing document, if any were previously open.
3. Editing Files

a. Within Nano, the user can create or edit text files using the available commands displayed at
the bottom of the editor.

b. Navigation within the file was accomplished using the arrow keys, allowing movement
throughout the text.

c. Made changes to the text were using the keyboard.

d. Saving changes to the file was achieved by pressing "Ctrl + O."

e. Use Command Ctrl + X” to exit Nano.

Step-by-Step Guide to Opening a Text Editor Using the GUI

1.Launching Ubuntu Linux and Accessing the GUI:

The process was initiated by launching VirtualBox on my computer and selected the Ubuntu
Linux virtual machine.

, I initiated the boot process was initiated by Clicking on the "Start" button of the virtual
machine.

2.Navigating to the Application Launcher:

Once Ubuntu had booted up, I located the application launcher, which was conveniently situated
in the taskbar at the bottom of the screen.

By clicking on the application launcher, I opened it, revealing a menu of available applications.

Finding the Text Editor Application:

Within the application launcher, I utilized the search function to locate the text editor application
quickly.

Typing either "Text Editor" or "gedit" in the search bar, I patiently awaited the appearance of the
search results.
Opening the Text Editor Application

Once the text editor application ("Text Editor" or "gedit") appeared in the search results, I
selected it by clicking on it.

This action launched the text editor application, which promptly displayed either a blank
document or any previously open document.

Text Editing

To create a new file, I navigated to the "File" option located in the menu bar at the top of the text
editor application.

Selecting "New" from the menu or using the associated keyboard shortcut, I initiated the creation
of a new file within the text editor.

To open an existing file, I again accessed the "File" option in the menu bar and chose "Open."
Then, I navigated to the desired file's location and selected it.

With the file open in the text editor, I utilized the available features and functionalities to edit the
contents of the file effectively.

Summary

Overall, I found the process of installing VirtualBox and Ubuntu to be straightforward. The

Ubuntu installation steps are very similar to installing Windows. The main challenge was getting used to

the Linux terminal andfinding applications, since I am used to a Windows environment. The terminal uses

a lot of unfamiliar text-based commands compared to the graphical interface I am used to. However, the

GUI still provides point-and-click interaction for basic tasks like opening apps. Ubuntu seems very user-

friendly and I can see similarities to Windows in terms of the dock, search bar, and general layout. After

more practice, I think I would get comfortable using both the terminal and the Ubuntu desktop

environment.
