More than just simplicity:
void:chris~ % perl -le '@a=(5,10,15,20); print scalar @a,"\n",$#a'
4
3
$# signifies the index of the last element in an arr
my final goal is to loop through each filename and count how many times each filename
appears, example:
archive/summer.html 2
arts.html 2
arttherapy.html 3.
for right now, I'm just trying to loop through the array @url.
Next step would be to compare whats in $line with what's in $url[$i] and if

It's working perfectly! :)
21$num = scalar(@url);
22print ("num = $num\n");
output:
num = 1
0 = archive
Hi Pam
$i is incrementing. Your loop starts with $i at zero, as shown by your
trace. The print statement executes, $i is incremented to 1, your test $i <
$num is made and found to be false ($i == $num) so the loop executes.
I'm not sure exactly what you're wanting. The line split(/ /, $line) will
you have told i not to increment past 0 but making $num your count. as your
print out shows, $num never gets past 1. I am not sure what you want $num to
be? do you want it to be a count of chars in the scalar string $url ? if so,
try length()
