From perldoc -f crypt,

$pwd = (getpwuid($<))[1];

system "stty -echo";
print "Password: ";
chomp($word = <STDIN>);
print "\n";
system "stty echo";

if (crypt($word, $pwd) ne $pwd) {
    die "Sorry...\n";
} else {
    print "ok\n";
}

Modify to suit your needs.

here is the answer based on ephemient's hint.. I dont need the first line that i removed and in if case ne suppose to be eq, probably means equal:)it looks it works..

system "stty -echo";
print "Password: ";
chomp($word = <STDIN>);
print "Password again: ";
chomp($pwd = <STDIN>);
print "\n";
system "stty echo";

if (crypt($word, $pwd) eq $pwd) {
    die "Sorry...\n";
} else {
    print "ok\n";
}

crypt is a red herring.

system "stty -echo";
print "Password: ";
chomp(my $password = <STDIN>);
print "\nPassword again: ";
chomp(my $check_again = <STDIN>);
print "\n";
system "stty echo";

if ($password ne $check_again) {
    die "Sorry...\n";
} else {
    print "ok\n";
}
