Executing Go code

There is another way to execute your Go code that does not create any permanent executable files – it just generates some intermediate files that are automatically deleted afterward.

The way presented allows you to use Go as if it is a scripting programming language like Python, Ruby, or Perl.

So, in order to run aSourceFile.go without creating an executable file, you will need to execute the following command:

$ go run aSourceFile.go
This is a sample Go program!
  

As you can see, the output of the preceding command is exactly the same as before.

Please note that with go run, the Go compiler still needs to create an executable file. It is because you do not see it, it is automatically executed, and it is automatically deleted ...
