See the below code to know if a file is a file or it is a directory
- If temp is a file output will be = “temp is a file”
 - If temp is a directory output will be = “temp is a directory”
 
package main
import (
    "fmt"
    "log"
    "os"
)
var (
    fileInfo *os.FileInfo
    err      error
)
func main() {
    info, err := os.Stat("temp")
    if os.IsNotExist(err) {
        log.Fatal("File does not exist.")
    }
    if info.IsDir() {
        fmt.Println("temp is a directory")
    } else {
        fmt.Println("temp is a file")
    }
}
