I don't know who I have to thank for this, but I think it was Anders who recommended that I look at perl after one of my last weird bash questions. I have a syntax question as I go though perl.
The situation. I read a file into an array and then go to reference each line.
my $NUM = 1; open FILE, ".bashrc" or die $!; my @array = <FILE>;
How is it legal that I can reference the array element either as @array[element] or $array[element]?:
while (@array[$NUM]) { print "$NUM : @array[$NUM]\n"; $NUM++; }
while ($array[$NUM]) { print "$NUM : $array[$NUM]\n"; $NUM++; }
From what I've read, it seems like the list $array[element] would just return the number of characters in the list $array[element] not the text itself. How should I think about this?
The other (serious) responders are accurate however I suggest you get a copy of the "Llama", i.e. Learning Perl, Randall L.Schwatz and Tom Pheonix, O'Reilly Press (I do not know whether there is a newer edition but I have the 3rd )...
