How to Use Julia on Ubuntu 22.04?

Here, various steps are demonstrated to use Julia on Ubuntu.

Step 1: Create a jl File

Using the nano text editor (any other text editor can also be used), create a new file with the extension of “jl”. In the below-mentioned command, a file with the name “myJuliaCode” is created with a nano text editor:

$ nano myJuliaCode.jl

Type the Julia code to display the message on the screen “Welcome to itsLinuxFoss” with the script below:

println(“Welcome to itsLinuxFoss”)

Save the file with the shortcut key of CTRL+S and exit the nano text editor with the shortcut key of CTRL+X.

Step 2: Run the Julia Code

To run the code, execute the command:

$ julia myJuliaCode.jl

The message has been displayed on the screen.
