Subject: tail + count
I wrote the following script
I wrote the following script as a windows tail + count function,
but it's too slow if the input is huge, how can it be improved?
if (!$ARGV[0]){
die(you've forgotten to enter the file name\n);
}
if (!$ARGV[1]) {
$n = 9; # output 10 rows by default
}
else {
$n = $ARGV

Hi John

@ARGV == 2 and my $n = pop || 10;
$n will be undefined if @ARGV != 2. Need something like:
$n = @ARGV == 2 ? pop : 10;
