Printing the last modified time of an existing file in Golang

Problem Solution:

In this program, we will get the last modified time of the existing file and print the result on the console screen.

Program/Source Code:

The source code to print the last modified time of the existing file is given below. The given program is compiled and executed successfully.

Golang code to print the last modified time of an existing file

// Golang program to print the last modified time
// of the existing file

package main

import "os"
import "fmt"

func main() {
	MyFile, err := os.Stat("Sample.txt")
	if err != nil {
		fmt.Println("File does not exist")
	}
	fmt.Println("File modified time:", MyFile.ModTime())
}

Output:

File modified time: 2021-04-05 06:30:26.512744872 +0000 UTC

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, os packages then we can use a function related to the fmt and os package.

In the main() function, we get the file pointer MyFile using os.State() for the existing file and then we get the last modified time of the existing file using the ModTime() function. After that, we printed the result on the console screen.
