How to get the absolute path from a relative path in Golang?

Syntax:

func Abs(path string) (string, error)

Consider the below Golang program demonstrating how to get the absolute path from a relative path?

package main

import (
	"fmt"
	"path/filepath"
)

func main() {
	// Getting absolute path of hello.go
	abs, err := filepath.Abs("./hello.go")

	// Printing if there is no error
	if err == nil {
		fmt.Println("Absolute path is:", abs)
	}
}

Output

Absolute path is: /hello.go

Note: The absolute path may different based on the path.
