GO Programming Language : First day with GO - Executing "Hello world" program.

OS : Ubuntu 12.04


Command to install
sudo apt-get install gccgo-go

Now type "go version" to know the version of  Go.
here is my output
go version xgcc (Ubuntu 4.9.1-0ubuntu1) 4.9.1 linux/amd64

Now its time to move on to our first hello world program.
Use any editor to create a Go file. Here I am using "vim" editor. Now create a Go file using following command. Depending upon the editor you are using following may differ.
vim hello.go

Now press i to enter INSERT mode and copy the following content

package main
import "fmt"
func main(){
   fmt.Printf("Hello, World\n");
}


Now press ":wq" to save and exit from editor.

That's all for now.
