I have inherited a lovely Nagios install where webinject (http://www.webinject.org/plugin.html) is used to run a series of 20 odd test cases.

Each test case is based on an xml file that contaisn the following stanza:
url=http://$hostname:port/path_to_app

In their great wisdom the local guys have decided to copy/paste/edit these xml so they have a set of files for each and every $hostname resulting in hundreds of files...

I _know_ there is a better way to do this if I could only learn/understand how to programmaticaly replace $hostname for each server I need to runsaid test for.

Any pointer would be great

it is possible to expand a scalar variable in a file using a regular expression with the e option:


my $hostname = 'example.com';
my $text = 'url=http://$hostname:port/path_to_app';
$text =~ s/(\$hostname)/$1/eeg;

How you apply that to your spefic requirements is the trick.
