There's no need for a temporary array when doing:
@reverse = reverse @data; @data = @reverse;
You can just do: @data = reverse @data and then print $data[0];. But to get the last item, you don't need to reverse the list -- just use the $#data or -1 index .. these are all the same:
print $data[-1]; print $data[$#data]; print pop @data; # NOTE: THIS SHORTENS THE ARRAY print scalar splice(@data,-1); # NOTE: SAME AS pop # or: @data = reverse @data; # OF COURSE, @data IS NOW MODIFIED print $data[0]; print shift @data; # NOTE: THIS SHORTENS THE ARRAY print scalar splice(@data,0,1); # NOTE: SAME AS shift


All of that is assuming you read your whole file into an array in memory, which is obviously costly for memory if the file is large ... A quick search revealed Read Last Line of A File Only
