for some help please

Hi everybody,

I have a problem when I run a very small program which is supposed to display a jpg file on screen. I get this error message:

sh: display: not found.

I'm using Ubuntu 8.04
Anybody has any idea about a possible resolution?

Much appreciate your help!

If you are the owner, then I don't know. But I get messages like that due to permissions settings.

Yes, it's on my machine and the machine is not on a network(yet). Does it have anything to do with the video card?

Can you give details of the program you have running? Do you have X running? What do you get when you run the following command in a terminal

echo $DISPLAY

[udaro]

This is what I get when I run the $DISPLAY command:

:0.0

The program that I compile and run is made of a very small C++ code which is ment to display a picture in jpg format on the screen, the picture being in the same folder.
I'm not sure if X is running as I don't know what X is yet...I'm too new to Linux...

If you already login as GUI mode then it might now allow you to start another display. Let us know if you have login in GUI mode.

login into TUI mode and then run your script check what it does.

OR

If you have sh running on the remote computer:

export DISPLAY=remote_comp_ip:0
xcalc &

OR
You also try opening another session of display manager and check if you can run your application on

export DISPLAY=localhost:0.1

Thanks everybody for your suggestions!

The actual problem was the ImageMagick application which was not installed on my system. Once I've installed it, all went perfect, so I assume now(I may be wrong though) that the "display" command was part of this application.
