I'm using kdialog a lot in a Bash script, and I always use the option --title="$title". So I made an alias, alias kdialog="kdialog --title=\"$title\"". The line alias|grep kdialog in the script outputs alias kdialog='kdialog --title="Audio Konvert 0.3.0"', but the title of a dialog created with kdialog --yesno "test" has a title of "Question - KDialog."

I'm trying to keep this all in one script.

Anyone?

Funny; it works for me. What version of KDE are you using?

a thing · Dec 27th, 2005, 8:37 AM

notroot[0:~]& rpm -q kdebase
kdebase-3.5.0-0.1.fc4
notroot[0:~]&

Mabe it's something wrong with somethinge else in the script...? Should I attach it (It's 37KB)?

Same KDE version I have, so it's nothing to do with 3.5. Have you tried doing this normally?

title="Audio Konvert 0.3.0"
alias kdialog="kdialog --title=\"$title\""
kdialog --yesno "Testing, 1, 2, 3."

Now try putting that in a shell script.

Ah. I see what you mean. Curious indeed. Perhaps aliases are meant only for interactive use?

Perhaps use a function instead?

(Toggle Plain Text)

function kdialog
{
    /usr/bin/kdialog --title="$title" $*
}

I've put in the full path of kdialog in the function, because otherwise the function will recursively call itself.

Functions will only be around for the duration of the script, I believe (unless you put them in bashrc or similar), but they are called the same way you would call a regular command or alias:

kdialog --yesno "Testing, 1, 2, 3."

Aliases are disabled for non-interactive shells (shell scripts) according to my book so I guess your experiment confirms it.

Good idea Arevos

(Toggle Plain Text)

#!/bin/bash
title="This is a test."
kdialog ()
{
	`kde-config --prefix`/bin/kdialog --title="$title $* #or $@
}
kdialog --yesno "Testing, 1, 2, 3."

almost works. The title works, but the content is "Testing," and excludes " 1, 2, 3."

`kde-config --prefix`/bin/kdialog --title="$title $* #or $@

Aren't you missing a " after $title? Could that be what's wrong with it?
