Introduction
This article covers the following tech skills:
The LabEx Linux Playground is an online environment that allows users to quickly experience various Linux-related technologies. It provides a sandbox-like environment where users can explore and experiment with Linux without the need to set up a local machine.
How to Use the Linux Playground
The Linux Playground in LabEx runs on the Ubuntu 22.04 operating system. To get started, you can create a “Hello World” project to familiarize yourself with the Linux Playground experience.
The LabEx Linux Playground offers three different user interfaces:
VS Code: Users can access the Linux environment through a web-based Visual Studio Code interface, allowing them to write, compile, and run code directly in the browser.
Desktop: The Linux Playground also provides a full-fledged desktop environment, similar to a traditional Linux desktop, where users can explore the file system, run commands, and use various applications.
Web Terminal: In addition to the graphical interfaces, the Linux Playground offers a web-based terminal, enabling users to interact with the Linux system using command-line tools and utilities.
To create a “Hello World” project in the Linux Playground:
Choose your preferred user interface (VS Code, Desktop, or Web Terminal).
Open a text editor or the terminal and create a new file named “hello.c”.
Inside the file, write the following “Hello World” program:
int main() {
printf(“Hello, World!n“);
return 0;
}
Compile the program using the gcc compiler: gcc hello.c -o hello.
Run the compiled program: ./hello.
You should see the output “Hello, World!” displayed in the terminal or console.
