Slide: Title	Welcome to the spoken tutorial on Installation of Rust on Linux OS.
Slide: Learning Objectives	In this tutorial, we will learn: How to install Rust. Create and execute a Rust file
Slide: System Specifications	This tutorial is recorded using: Ubuntu Linux OS version 18.04 Rust version 1.47.0 Visual Studio Code version 1.45.0 (code editor) However you may use any other editor of your choice.
Slide: Pre-requisites	To practice this tutorial, You need an internet connection to install the necessary packages and You should be familiar with basic Linux commands. If not, please go through the prerequisite Linux tutorials on this website.
Slide: Code files	The files used in this tutorial are available in the Code files link on this tutorial page. Pls download and extract the file. Make a copy and then use it for practising.
Only narration	Let us begin with the installation of Rust.
Show commands.txt in text editor	I have opened the Commands.txt file in a text editor on my machine. And I will use the same file to copy-paste the commands during the demonstration. Shortcut to paste commands on the terminal is Shift, Ctrl and V keys.
Narration only	Let us begin.
Press Ctrl+Alt+T keys	Open the terminal by pressing Ctrl,Alt and T keys simultaneously on the keyboard. Ensure that you have root permissions to run the commands.
Only Narration	Here onwards, please remember to press the Enter key after typing each command.
[Terminal] Type: sudo apt-get install curl -y [Enter]	We will be installing Rust with the help of the curl command line tool. So, we have to first install curl if we haven’t done so earlier. To do so type the command as shown on the terminal.
[Terminal] Enter admin password	If prompted enter the admin password to proceed further.
[Terminal] Type: curl --proto '=https' --tlsv1.2 https://sh.rustup.rs -sSf | sh [Enter]	We have successfully installed curl. Next let us download and install Rust using Curl. To do so type the command as shown on the terminal.
Only Narration	The download may take some time depending upon your internet speed.
[Terminal] Highlight one by one: Proceed with installation (default) Customize installation Cancel installation	Once the package is downloaded, we will be prompted to choose one of the following options: Proceed with installation (default) Customize installation Cancel installation
[Terminal] Type: 1 [Enter]	To proceed with the default installation, type 1 and press Enter.
[Terminal] Highlight: Rust is installed now. Great!	We have successfully installed Rust.
[Terminal] Type: sudo reboot [Enter]	Once the installation is done, we need to restart our computer. To do so, type sudo reboot in the terminal. This will restart your computer.
Press Ctrl+Alt+T keys	Once you have restarted the computer, open the terminal again
[Terminal] Type: rustc --version [Enter]	Now let us cross verify the Rust installation. Type the command as shown in the terminal.
[Terminal] Highlight: rustc 1.47.0	This command shows the version of Rust installed in your computer. The version number may be different in your case.
[Terminal] Type: rustup [Enter]	Now type rustup on the terminal.
Only narration	This shows us a list of Rust commands to run. rustup is responsible for the complete Rust installation using the curl command.
Slide: Rust Update rustup update [Enter]	If you wish to update your Rust version, then execute this command on the terminal.
Slide: rustup toolchain list	rustup toolchain command lists the various toolchains of Rust installed in your machine. For now, I have only one stable version installed. If you have any other versions, then that version would be displayed.
Slide: cargo	cargo is a package manager to maintain a Rust project with dependencies.
[Terminal] Type: cargo [Enter]	You can check whether cargo is installed or not using the cargo command in the terminal. This shows a list of commands which can be executed using cargo.
[Terminal] Type: cargo --version [Enter]	This command shows the version of the cargo package manager installed in your machine.
Slide: Common Errors After Installation	System restart is required after installing rust. If not, we could land with these errors Rustup Rustc Cargo - command not found
Only narration	Next let us learn how to create and execute a Rust file.
Open Visual Studio Code editor.	You may use any editor of your choice. I will use Visual Studio Code editor for this demonstration.
[Editor] Type: fn main() { println!("Hello World"); }	In the code editor, type the code as shown.
[Editor] Highlight: fn main(){ }	This is our main function.
[Editor] Highlight: fn	The keyword - fn is used as a syntax to create a function in Rust.
[Editor] Highlight: main()	main indicated the name of the function. The Rust execution starts from the main function.
[Editor] Highlight: { }	The code written in between the open and closed curly braces would be the function body.
[Editor] Highlight print!	Print!() is the print function in Rust.
[Editor] Highlight Hello World	Here we have written Hello World in double quotes as a parameter in the function call.
[Editor] Highlight print!(“Hello World”)	So, when we run the program, hello world gets printed.
Press Ctrl + S	Let us save the file by pressing Ctrl + S keys together.
Point to Save As dialog box	Save dialog box opens.
Point to Name >> type "hello-world.rs"	In the Name field type the name of the file as hello-world.rs
Highlight .rs	The extension .rs states that this is a Rust code file.
Select Desktop location Create MyRustProject folder	On the left side, I’ll select Desktop and then create a folder named MyRustProject.
Point to MyRustProject	From now on, I will be saving my Rust files in this folder.
Click on Save button.	Then click on the Save button at the top right corner of the dialog box.
	We have created a Rust file and have written the hello world program. Now, it’s time to compile and run the file.
Switch to terminal	Switch back to the terminal.
[Terminal] Type: cd Desktop/MyRustProject [Enter]	Using cd command go to the location where the Rust file is saved. In my case, it is MyRustProject on the Desktop.
[Terminal] Type: rustc hello-world.rs [Enter]	To compile type rustc space filename with extension .rs In my case it is hello-world.rs
[Terminal] Type: ./hello-world [Enter]	The compilation is done without any error. Now, to run type the dot slash filename and press Enter. In my case it is ./hello-world
[Terminal] Highlight: Hello World	Hello world text gets printed.
Slide: Common Errors sudo apt install build-essential	You could land up with this error while compiling - linker ‘cc’ not found. It means you don’t have gcc in your machine. To resolve this, install the build essentials with this command.
Only narration	We have successfully installed Rust and executed the hello world program. With this we have come to the end of this tutorial, let’s summarize.
Slide: Summary	In this tutorial, we have learnt How to install Rust Some basic Rust commands How to overcome common errors during installation Create and execute Rust file
Slide: Assignment	As an assignment, Create a file assignment.rs Print - ‘Welcome to Spoken Tutorials!’ Compile and execute the file. Observe the output in the Terminal
