This is annoying me. I'm sure I'm f@#ing it up, please correct me.	Can't Post

Code

cat /tmp/stuff |  perl -e  '

  while (<STDIN>)  {  
     my ($url) = $_ =~ /https?:\/\/(\S+)\//; 
     print "$url\n";  
     if ($urlhash{$url}) {  
          $urlhash{$url}++;

It works fine if I do this:

Code

cat /tmp/stuff |  perl -e 'my %urlhash ;  
while (<STDIN>) {  
     my ($url) = $_ =~ /https?:\/\/(\S+)\/t/;  
     print "$url\n";  
     if ($urlhash{$url}) {  
          $urlhash{$url}++;  
     } else  {  
          $urlhash{$url} = 1; 
     } 
} '

Hi,
I have heavily edited your post to add code tags as well as line returns and indentation in the code, to try to make your post more readable. Please use code tags next time you post here.

Even after having reformated the post to make it more readable, I still don't understand what you want. What is your problem? What is your question?

I'm just trying to parse an apache log. In this case, just trying to extract the hostname from the GET, if it exists. After that I'm counting.

It works for a lot, but not for everything. I'm confused as to why it doesn't work. It seems that it's not matching the slash in cases similar to the one I noted.

I suspect that you problem is the greedy match. Try:

Code

my ($url) = $_ =~ /https?:\/\/(\S+?)\//;

Good Luck,
Bill

Beautiful.

I would have thought an explicit match would override the greed, but I'm for what works.

Thanks.

I'm just trying to parse an apache log.

Rather than rolling your own parser, why not use one that has been tested by tens of thousands of people.
