Do NOT read a file into an array, unless it's really REALLY *REALLY*
necessary. There are almost ALWAYS better ways to do things.
That said, I wouldn't do:
@lines = <FILE>;
$count = @lines;
I would use either the FAQ's solution with sysread(), or a simple while
loop:
1 while <FILE>;
$count = $.;
For more on $., read perlvar.
