How to create a temp file in the specified temp directory in Golang?

Problem Solution:

In this program, we will create a temp directory at the specified path and create a temp file. After that, we will print the name of created temp directory and temp file on the console screen.

Program/Source Code:

The source code to create a temp file in the specified temp directory is given below. The given program is compiled and executed on the ubuntu 18.04 operating system successfully.

Golang code to create a temp file in the specified temp directory

// Golang program to create a temp file
// in the specified temp directory

package main

import "io/ioutil"
import "fmt"

func main() {
	tempDirLoc, err := ioutil.TempDir("/home/arvind/", "DirName")
	if err != nil {
		fmt.Println(err)
	} else {
		fmt.Printf("Created temp directory is (%s)\n", tempDirLoc)
	}

	filePtr, err := ioutil.TempFile(tempDirLoc, "tempFile")
	if err != nil {
		fmt.Println(err)
	}
	fmt.Println("Created temp file:", filePtr.Name())

	filePtr.Close()
}

Output:

Created temp directory is (/home/arvind/DirName707004040)
Created temp file: /home/arvind/DirName707004040/tempFile579513927

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 that includes the files of package fmt then we can use a function related to the fmt package.

Here, we also imported the io/ioutil package to use TempDir() and TempFile() functions.

In the main() function, we created temp directory at "/home/arvind/" directory using ioutil.TempDir() function and then we created a temp file in created temp directory using ioutil.TempFile() function. After that, we printed the created temp directory and temp file name on the console screen.
