a cron job needs a perl script to execute

Hello evreyone,

this is my first post, and to say i'm new to this is an understatement.
I know very little about perl scripts and hope some one can help me.
i'm looking to get a script that a cron job can execute.

what the script needs to to is
1) connect to a mysql database
2) go to a table called products
3) grab the products marked as free and 1 week old and delete that record from the table

Since the products are added on a daily bassis, it would be nice to run the cron job every day.

the database reads
free products are marked as ( prodtype )
creation date is marked as ( proddate )
and there is one called ( timetolive )

So far by reading what i can i have the perl script started.

-----------------------------------------
#!/usr/bin/perl

# PERL MODULES WE WILL BE USING
use DBI;
use DBD::mysql

# CONFIG VARIABLES
$platform = "mysql";
$database = "nameofdatabase";
$host = "mysql.domainname.com";
$port = "3306";
$tablename = "products";
$user = "myusername";
$pw = "password";

# DATA SOURCE NAME
$dsn = "dbi:mysql:$database:$host:3306";

# PERL DBI CONNECT
$connect = DBI->connect($dsn, $user, $pw);

}

-------------------------------------------

Now from what i know this could be all wrong

the path to the file that the cron job follows is
/home/myusername/domainname.com/cgi-bin/nameofscript.pl

i also need to use a crontab to set up the daily time to execute the perl script.


please be gentle, I bow down to Newbies Smilie

NAME
build-lives-rfx-plugin - builds rendered effects for LiVES SYNOPSIS
build-lives-rfx-plugin script_name [plugin_dir] -get section file DESCRIPTION
This perl script is used by LiVES to compile an RFX (rendered effect) plugin for LiVES. It is generally called from build-lives-rfx-plugin- multi for a script which has a language code representing LiVES-perl. The script_name must be the full (absolute) path to the plugin script, and plugin_dir can be used to specify the output directory where the compiled plugin should be generated. If plugin_dir is not defined then /tmp is assumed. The second variant with -get is used to print out a script section from a plugin script to stdout. It is generally only used internally by LiVES. Return values The script returns the following values 0 - success 1 - the value of a trigger was greater than the number of parameters 2 - a value could not be read from the script file 3 - the language code of the plugin script was not equivalent to LiVES-perl 4 - the API version level of the plugin script was invalid 5 - the <define> section was missing from the plugin script SEE ALSO
