Getting the information about the current user in Golang

Problem Solution:

In this program, we will use user.Current() function to get information about the current user. The user.Current() returns the structure that contains user information.

type User struct {
	Uid      string // the user ID
	Gid      string // the primary group ID
	Username string // the login name
	Name     string // user's real or display name
	HomeDir  string // user's home directory
}

Program/Source Code:

The source code to get the information about the current user is given below. The given program is compiled and executed on the ubuntu 18.04 operating system successfully.

Golang code to get the information about the current user

// Golang program to get the information
// about the current user

package main

import "fmt"
import "os/user"

func main() {
	info, err := user.Current()

	if err != nil {
		panic(err)
	} else {
		fmt.Println("Current User Info: ", info)
	}
}

Output:

Current User Info: &{1000 1000 arvind Arvind Gaur /home/arvind}

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/user" package to use the Current() function.

In the main() function, we got the information about the current user using the user.Current() and printed the result on the console screen.
