We've installed PSudo, It's time to try! Traditionally, When starting a new programming language, we write down a little program that prints Hello, world! on a terminal. So, Let's try it!

Note: This book assumes you to know command-line interface. This book won't limit you to use editor or development tools and place the file where. Just develop in your favorite environment.

Note: PSudo never requires folder because codes and compiler configurations are stored in a single file. But we recommend you to create a folder and store all the PSudo codes on it. Because it is easier to organize.

First, create a folder where store code. It's not a matter where to place code, But this book assumes that you're creating a psudo-solutions folder in your home directory. Open a terminal and enter following commands to create the folder.

for Linux, macOS, Windows:

mkdir ~/psudo-solutions
cd ~/psudo-solutions

for Windows CMD:

mkdir "%USERPROFILE%\psudo-solutions"
cd /d "%USERPROFILE%\psudo-solutions"

Next, Make a new source file and call it hello-world.ps. PSudo file should end with .ps extension. If you're using more than one word on your file name, use the hyphen to separate them.

Now open the file and write down below codes.

output "Hello, world!"

Save the file and go back to your terminal window. Then run following command.

psudo run hello-world.ps

Whatever your OS is. It will print Hello, world on your terminal. If you didn't see these output, Go to Chapter 1: Installation - Troubleshooting part to get help.

However, if you did these jobs successfully, Congratulations! You've written a PSudo Solution! Which means, from now on you're PSudoer - welcome!
