How to delete a file using the os package in Golang?

To delete a file using the os package in Golang, you can use the Remove or RemoveAll function provided by the package. Here's an example demonstrating both approaches:

package main

import (
	"fmt"
	"os"
)

func main() {
	// Define the path and name of the file to delete
	filePath := "path/to/file.txt"

	// Remove the file
	err := os.Remove(filePath)
	if err != nil {
		fmt.Println("Error deleting file:", err)
		return
	}

	fmt.Println("File deleted successfully.")

	// Alternatively, you can use RemoveAll if you need to remove directories as well
	// RemoveAll(path) removes path and any children it contains
	// It is similar to running "rm -rf" on the command line
	dirPath := "path/to/directory"

	err = os.RemoveAll(dirPath)
	if err != nil {
		fmt.Println("Error deleting directory:", err)
		return
	}

	fmt.Println("Directory deleted successfully.")
}

Ensure that you have the necessary file/directory permissions to delete the file/directory.
