Bashscripts.org

Hello,

I have a simple script that display a form. It looks perfect when executed 'manually'. However, when the exact same script is executed by rc.local, it is not displayed correctly.

See link here for screen shots: http://api.virtualcad.com/misc/display.jpg

What I have learned so far, is that the terminal/environment is not the same when a program is executed by rc.local and that I may need to execute my script using a 'pseudo-tty wrapper'. However, I can't find any answers - perhaps I am not using the right keywords, but Google isn't helping.

Can someone steer me in the right direction?

Thanks,

Eric

This is not really a bashscript problem.
But I'll give it a shot anyway since I'm quite sure this is a $TERM problem.

Try writing at the top of your script (or rc.local):

Hello Fredrik,

Thanks for your help.

I had tried that. It has an effect (so maybe it is the right direction) but still has display issues.

See the image here: http://api.virtualcad.com/misc/dialog.jpg

The difference this time is that now when I execute the script manually, I see the exact same thing. At least it is consistent now.

It is clear the issue now is some sort of 'character mapping' problem.

Have you seen this before?

Thanks in advance for any help you can offer,

Eric

Well it's basically how the terminal interprets nCurses.

Usually that fixes those kinds of issues... but apparently you need to set some other kind of terminal.

Remove it and echo $TERM when it works as it should and you should be able to figure out which kind of terminal should be set.
