Command Question


I am new to script writing but I have worked out half of what I want to do and wonder if someone can get me the rest of the way??

Firstly, I am using the new Mandriva with KDE4.2.

I have written the following script which is downloading a Radar image of where I live to get notice of rain falling in my area. It downloads an image every ten minutes and places it in a folder in my home directory as "weather.gif"
Here is the script.

!/bin/bash

while x=0; do wget --force-clobber --output-document=/home/vaughan/Weather/weather.gif http://www.bom.gov.au/radar/IDR083.gif?20090416082435 ; sleep 600; done

This part works.


But what I want to do is to show the photo on my desktop which is updated every 10 minutes, much like what gkrellkam does, however I don't want to use Gkrellkam anymore for different reasons.

I have tried using a plasmoid which comes with kde4 called "picture frame". Picture Frame has 2 basic settings "slideshow" and "Image" But with just one photo in the folder slideshow won't update every 10 minutes even though the photo is renewed in the folder every 10 minutes.

Can someone help me how to get the downloaded photo to be shown on the desktop and updated every 10 minutes?? either in script form or a program that would do the job?

Thanks in advance

I am not sure about the details of this, but have you looked at "display"? (Part of the imagemagick suite)

When you say "update every 10 minutes", I assume you mean refresh the displayed image every time that a new one is downloaded.

Thanks for the idea but Imagemagik just crashes if I set it to slideshow and there is only one photo in the folder.

Any other ideas????

If you are downloading a new picture every 10 minutes, why do you need a slideshow? Just display the pictures as they arrive.

Will it just display the 1st pic only or will it update itself periodically and if so how often??

No it won't work. It only displays the photo which is there when I first start Imagemagick up. As the photo re-news Imagemagick fails to refresh.

Thanks for the help though.

In the loop that downloads the picture, add a statement that displays it. Every time through the loop, it should display the new file. (Maybe you need to kill the display of the last file first.)

I am not sure I would expect it to.....

I've been following this thread out of interest as I do something similar but much simpler. Just a one line bash script to open a browser daily to a weather site. Are your intentions to save each image in your weather directory?

Check out this list of bash commands: http://www.ss64.com/bash/

Click on 'kill' in the list for an explanation of its use. You'll need to get the pid to do this. Sorry but, I don't know how to get it to display.

I looked thru ImageMagick and could not find anything more elegant than just killing the window.
