Golang create temporary directory

temp_dir.go

package main

import (
	"fmt"
	"io/ioutil"
	"log"
)

func main() {
	tmp, err := ioutil.TempDir("", "")
	if err != nil {
		log.Fatal(err)
	}

	fmt.Println(tmp) // /var/folders/k1/m2rmftgd48q97pj0xf9csdb00000gn/T/254614131
}

In case someone else lands here searching for this: as of Go 1.17 ioutil.TempDir() is deprecated in favour of os.MkdirTemp() (same arguments, same behaviour, drop-in replacement).
