To create a command line script to make someting in RT you have to call initialization methods:

• CleanEnv – clean out user’s environment variables: PATH, ENV, SHELL, CDPATH, IFS.
• LoadConfig – loads config. Basically do just use config;.
• DBConnect – calls RT::Init() which sets connection to the database, creates two users – system user and nobody and initializes lgging system.

Each RT (except RT::Users and RT::CurrentUser) class needs to have a user object as parameter in its constructor:

To get an user object use CLI method GetCurrentUser:

It uses Perl function

which returns a record from /etc/passwd according to real user ID (UID). UID can be retrieved from special Perl variable $< . So, you’re lucky if you have the same user name in RT and on the computer where the script will be run. Otherwise you should load the user object directly:

Let’s put all them together:

#!/usr/bin/perl -w
use strict;
use warnings;
use lib ("/opt/rt2/lib", "/opt/rt2/etc");
use RT::Tickets;
use RT::Interface::CLI  qw(CleanEnv LoadConfig
                         DBConnect GetCurrentUser);

#Clean out environment
CleanEnv();

#Load etc/config.pm
LoadConfig();

#Connect to the database
DBConnect();

my $curr_user = GetCurrentUser();

#
# Do something
#

# Disconnet from the database
$RT::Handle->Disconnect();
