gksudo with stdin redirection

How do I fix this test program?

Code:

#!/bin/bash

gksudo bash <<EOF

ifconfig
echo "I'm" root!
touch /tmp/helloworld

EOF

I'll replace the code here, clearly. I have a client that needs a brief script that runs as root (Kubuntu). This works with sudo, but I cannot expect them to open the shell and type a command. This needs to be point and click.

I've also tried kdesudo. They seem to accept the password, and then freeze. I'm missing something, probably something simple.

Imho, a nice solution would be to get gksudo out of the script (maybe you can put it in the launcher command section).

However, you can pass some code to a bash call through the -c option:

Code:

bash -c "foo;bar"

In your case:

Code:

gksudo -- bash -c '
ifconfig
echo "I'm" root!
touch /tmp/helloworld
'

"--" is used to inform gksudo not to interpret -c as one of its options

I need a gui program which gains root privileges and then continues running my short shell script. The user is in the sudoers group (capable of sudo).

You were very vague about the launcher. While I think that might be doable, I'll need to go back onsite to check. I'm not used to dealing with Gnome, and I would really like to have this script self contained. In other words, I'll look into it, but I would like to get my script working as intended.

You could use xterm.

Put your commands in a file, say test.sh (kdesu should work on Kubuntu):

Code:

gksudo /sbin/ifconfig  
echo "I'm root"
touch /tmp/helloworld
...

and create a "link to application" on the desktop. Under the application tab, on the command line put:

Code:

xterm -hold -e "/path/to/test.sh"

This should pop up an xterm window and all the user will have to do is close it.
