Problem in running Cron job

[rinjo]

Hi All,

I am trying to run GIMP using a Cron job, the job gets submitted/executed in time, but its unable to open gimp display.
I get the following mail.

Subject: Cron <rinjo@localhost> /usr/bin/gimp-2.4
Date: Thu, 17 Dec 2009 21:04:01 0530 (IST)
Content-Type: text/plain; charset=UTF-8

X-Cron-Env: <SHELL=/bin/sh>
X-Cron-Env: <HOME=/home/rinjo>
X-Cron-Env: <PATH=/usr/bin:/bin>
X-Cron-Env: <LOGNAME=rinjo>
X-Cron-Env: <USER=rinjo>

cannot open display:

Can anyone help me solve this issue, so that the display is opened.
Basically my idea is to run a job that will trigger some display based executable.

regards
Rinjo

I made a script that that calls gims and got following error:

GIMP could not initialize the graphical user interface.
Make sure a proper setup for your display environment exists.

Once I exported the DISPLAY env var in the script. it worked fine.

export DISPLAY=:0.1

/usr/bin/gimp

ps. I am using CentOS release 5.4, hope it works for you.
