activate a shell script with a desktop link?

[siggi]

Desktop: Kubuntu, Version: 7.04 Feisty Fawn
************************************

Hi,

I would like to run a shell script using a desktop link to that script, avoiding to open a terminal and to type the command. However, being rather new to Linux/Kubuntu, till now this fails. How can I do it?

Background
---------------

The script I created is /usr/local/sbin/downUpWLAN:

#!/bin/bash

sudo ifdown wlan0
sleep 30
sudo ifup wlan0

exit 0

It is executable:

-rwxr-xr-x 1 root root 55 2007-08-08 21:31 downUpWLAN

In sudoers, I did set access rights to downUpWLAN for all users (last line) using "sudo visudo":
#

/etc/sudoers
#
# This file MUST be edited with the 'visudo' command as root.
#
# See the man page for details on how to write a sudoers file.
# Host alias specification

# User alias specification

# Cmnd alias specification

# Defaults

Defaults !lecture,tty_tickets,!fqdn

# User privilege specification
root ALL=(ALL) ALL

# Members of the admin group may gain root privileges
%admin ALL=(ALL) ALL

# All users may run downUpWLAN
%users ALL=NOPASSWD: /usr/local/sbin/downUpWLAN

If I type in a terminal "downUpWLAN", the script works beatuifully:
* I have to type in my log-in password
* then ifdown wlan0 starts, outputs messages
* after 30 seconds ifup wlan0 starts, outputs messages
* now my wireless internetconnection is active, if it wasn't before

The problem
---------------

If I place a link from downUpWLAN to my Desktop using
<Alt>+<F2>kdesu konqueror

...nothing happens if I klick this link. No demand for the password, no message output, no network activation. However, when I put a line into downUpWLAN such:

echo Hello >> /<path to my desktop>/output.txt

the file output.txt. is created on my desktop. Thus, linking works for a text output. But how can I get the commands "sudo ifdown wlan0" and "sudo ifup wlan0" to work?

Any suggestions, please?

Case somebody wants to know
---------------------------------------
I connect to the internet wirelessly with AVM Fritz!Stick USB/Fritz!Box WLAN. The connection is steady and runs smoothly, once established. But most often, first I have to use the two "ifdown..." "ifup..." commands after a start or reboot. I want to stick to this routine for some time to better get to know my system and learn some scripting on the way.

Thanks,

Siggi

# For one script in particular:

From Konqueror, "drag & drop" the script file to the panel, fill in the form popping-up thereupon, select "Run in terminal" - and that's it

or you can create a "*.desktop" file that opens "sh /PathToScript/script"

Sorry, nothing like this is popping up! The only choices I have are

* Copy
* Link
* Escape

I tried both "konqueror" and "kdesu konqueror", to no avail!

What is going wrong, please?

Terrific! I ended up on my desktop with a blue cogwheel that does exactly what I want. Thanks

Being pretty much a newbie it took quite some trial and error to advance from a simple textfile to a link to an application. Learned quite something!

have a nice evening if you are this side of the ocean
