Top Forums Shell Programming and Scripting Get only domain from url file bind Post 302960959 by Don Cragun on Sunday 22nd of November 2015 02:00:00 PM

Back in post #14 I showed you a way to get rid of lots of extra processes you are invoking for each line you read. In post #16 you said my suggestion improved performance of your script by a factor of 5. But, in your latest script in post #24 in this thread, you have thrown away that improvement and added several more duplicated invocations of geoiplookup piped through various combinations of awk, cut, awk again, and tr. Why? If you would have taken that earlier advice and applied it to the geoiplookup invocations as well, you would easily get an improvement by at least a factor of 10.

Your script in post #24 has two distinct parts. The 1st 49 lines process the stuff we have been talking about in this thread. The last line processes a file that is not mentioned in the rest of the script. Why not move that command to the start of your script and run it asynchronously (and add a wait at the end of your script if your script should not be allowed to terminate before that command completes)?

How many cores can you use on your system? If you want to run thirty copies of your script simultaneously, you will probably be fighting against yourself if you don't have at least thirty cores at your disposal.

URI::URL(3)						User Contributed Perl Documentation					       URI::URL(3)

NAME
URI::URL - Uniform Resource Locators SYNOPSIS
$u1 = URI::URL->new($str, $base); $u2 = $u1->abs; DESCRIPTION
This module is provided for backwards compatibility with modules that depend on the interface provided by the "URI::URL" class that used to be distributed with the libwww-perl library. The following differences exist compared to the "URI" class interface: o The URI::URL module exports the url() function as an alternate constructor interface. o The constructor takes an optional $base argument. The "URI::URL" class is a subclass of "URI::WithBase". o The URI::URL->newlocal class method is the same as URI::file->new_abs. o URI::URL::strict(1) o $url->print_on method o $url->crack method o $url->full_path: same as ($uri->abs_path || "/") o $url->netloc: same as $uri->authority o $url->epath, $url->equery: same as $uri->path, $uri->query o $url->path and $url->query pass unescaped strings. o $url->path_components: same as $uri->path_segments (if you don't consider path segment parameters) o $url->params and $url->eparams methods o $url->base method. See URI::WithBase. o $url->abs and $url->rel have an optional $base argument. See URI::WithBase. o $url->frag: same as $uri->fragment o $url->keywords: same as $uri->query_keywords o $url->localpath and friends map to $uri->file. o $url->address and $url->encoded822addr: same as $uri->to for mailto URI o $url->groupart method for news URI o $url->article: same as $uri->message SEE ALSO
