$ go version

This will output the version number of Golang.

Compilation of Golang project

Now that you have completed the installation of the Golang compiler, the following will demonstrate how to compile a simple Golang project.

1. Preparing the project

Before executing the demonstration in this article, please first create a simple Golang project named hello.go. The following commands can be used.

$ mkdir hello
$ cd hello
$ touch hello.go

and add the following code in the hello.go file.

package main

3. Run the project

Now you can run the hello project, use the following command.

$ ./hello

This will output:

Hello, Golang!
