Writing Utility Scripts

setting.pl Make a copy of sbin/_utility.skeleton /data/webgui/sbin$ cp _utility.skeleton setting.pl Find # Do your work here section Use any part of WebGUI s API to access or change the data There are other sections that mark simple edits to make

Finished code use lib "../lib"; use strict; use Getopt::Long; use WebGUI::Session; my $session = start(); for my $setting (@ARGV) { print $setting. -. $session->setting->get($setting). "\n"; # Do your work here finish($session); Output /data/webgui/sbin$ perl setting.pl --configfile=www.mysite.com.conf companyname companyname - My Company

Allow changing settings use lib "../lib"; use strict; use Getopt::Long; use WebGUI::Session; my $session = start(); for my $setting (@ARGV) { if ($setting =~ /^(\w+)=(.*)/) { my ($name, $value) = ($1, $2); print $name.

apacheauth.pl Serve static content or anything else apache handles Authorize access based on WebGUI groups Example: Control subversion access How? Write an authentication handler, so Apache recognizes WebGUI s users Write an authorization handler, to allow for deny access based on groups

Utility Scripts Interact with WebGUI in an automated fashion Perform maintenance on a WebGUI site Interact with the local file system and OS Add new functionality using WebGUI s API
