Getting the hostname of the computer in Golang

Problem Solution:

In this program, we will get the hostname of the computer using os.Hostname() function and then print the result on the console screen.

Program/Source Code:

The source code to get the hostname of the computer is given below. The given program is compiled and executed on the ubuntu 18.04 operating system successfully.

Golang code to get the hostname of the computer

// Golang program to get the
// hostname of the computer

package main

import "fmt"
import "os"

func main() {
	Hostname, err := os.Hostname()
	if err != nil {
		panic(err)
	}

	fmt.Printf("HostName is: %s\n", Hostname)
}

Output:

HostName is: ubuntu

Explanation:

In the above program, we declare the package main. The main package is used to tell the Go language compiler that the package must be compiled and produced the executable file. Here, we imported the "fmt" package to use the Printf() function and we also imported the "os" package to use the Hostname() function.

In the main() function, we used os.Hostname() function to get the hostname of the computer and print the result on the console screen.
