Why infinite loop appears to the script?
There’s no infinite loop. For the input provided, it creates a hash with 239,517 elements, then dumps the hash. The output starts appearing almost immediately.
Could you please tell me what does the
$F[2]..$F[3]mean?
In list context, if $F[2] and $F[3] are numbers, it returns a sequence of numbers from $F[2] to $F[3] inclusive.
$ perl -E'for my $i (10..15) { say $i }'
10
11
12
13
14
15
