Copy to a brand new file solely these tapes which have a sure sequence of characters – Getting Assist

Hiya. I need assistance. In my code, the desired .txt file (with textual content) is copied within the specified path to the listing, however the code must be modified in order that solely these tapes which have a sure sequence of characters are copied to the brand new file. This may be achieved, I feel, with Graph, however I don’t know the way
I’ll be pleased about your assist

	learn := make([]byte, 0, 64)
	var title, name2 string
	var path string
	fmt.Println("Set technique to copy file:  ")
	fmt.Scan(&path)
	fmt.Println("Set file title to repeat:  ")
	fmt.Scan(&title)
	wd, err := os.Getwd()
	if err != nil {

		return
	}
	os.Chdir(path)
	file, err := os.OpenFile(title, os.O_RDWR|os.O_CREATE, 0755)
