Golang : Check if a directory exist or not
In this short tutorial, we will learn how to check if a parameter passed as argument is directory or not. It is pretty straight forward by using the os.Stat.IsDir() function
checkdir.go
package main
import (
"os"
"flag"
"fmt"
)
func main() {
flag.Parse() // get the arguments from command line
source_dir := flag.Arg(0) // get the source directory from 1st argument
fmt.Println("Source :" + source_dir)
// check if the source dir exist
src, err := os.Stat(source_dir)
if err != nil {
panic(err)
}
// check if the source is indeed a directory or not
if !src.IsDir() {
fmt.Println("Source is not a directory")
os.Exit(1)
}
}
Hope this will be helpful.
