To confirm, type yes: (y/N)

Treba mi pojasnjenje za ovo. Jel ovo y/N ono sto korisnik upisuje ili je to dio teksta. jel mogu upisati samo yes, ili samo y ili oboje?

[ksokolic]

y/N je ono što user upisuje. Može upisati ili yes ili y, ako ne upiše ništa smatramo da je odustao od naredbe (tj kao da je upisao no).
