How to recursively walk through a directory and its subdirectories using the os package in Golang?

To recursively walk through a directory and its subdirectories using the os package in Golang, you can use the filepath.Walk function. Here's an example:

package main

import (
	"fmt"
	"os"
	"path/filepath"
)

func visit(path string, info os.FileInfo, err error) error {
	if err != nil {
		return err
	}

	// You can perform actions on each visited file or directory here
	fmt.Println(path)

	return nil
}

func main() {
	root := "." // Change the root directory as per your requirement

	err := filepath.Walk(root, visit)
	if err != nil {
		fmt.Printf("Error walking the path %s: %v\n", root, err)
	}
}

In this example, the visit function is called for each visited file or directory. It receives the path, file info, and any error that occurred during the visit.

You can perform any desired actions on each visited file or directory within the visit function. In this example, it simply prints the path of each visited item.

Make sure to update the root variable to specify the directory you want to start the recursive walk from.
