Uri showed right above how to avoid using $_. eg instead of:
foreach ( @hping_array ) {
$_ + 10;
#...60 lines of code
print "$_\n";
}
do:
for my $ping_result ( @hping_array ) {
$ping_result + 10;
#... 60 lines of code
print "$ping_result\n";
}
You will appreciate this in longer programs, as it is very clear as to
what the variable is for, and which scope it belongs to.
