I noticed that after using "getopt" at the start of the code reduces $#argv to "0",as a result my below code fails,basically I want to check "if the option f exists then the $#ARGV needs to 7" and "if the option f does not exist the $#ARGV needs to be 5".I tried moving "getopt" code down but the option check fails.Can anyone let me know how can I achieve this? 

use Getopt::Std;
use Data::Dumper;
#Getting the command-line options
my %options=();
getopt("fdrv",\%options);
#print  Dumper( \%options );
#USAGE
if (exists $options{f}) {
if ($#ARGV !=7) {
print "USAGE withouf option f";
}
}

if (not exists $options{f}) {
if ($#ARGV !=5) {
print "USAGE without option f";
}
}
