Re: Problem running script from GUI

Post the script if you don't mind, so we can look at it.

Re: Problem running script from GUI

Are the permissions ok? Is it executable?

Re: Problem running script from GUI

HI,

Yes, the script is executable and runs perfectly fine from a fresh command prompt without asking for a password.

The script is the one for the DVD mounting that I wrote before...
sudo umount /media/cdrom0
sudo mount -t iso9660 /dev/scd0 /media/cdrom0
sudo umount /media/cdrom1
sudo mount -t iso9660 /dev/scd1 /media/cdrom1
...and executes fine as the sudoers entries allow me to use mount and umount without a password prompt.

The key issue is, if I tell the link to run the script as another person, it asks for the password and then runs it; but if I tell it not to run as another user, I get the error message mentioned earlier.

Re: Problem running script from GUI

First of, do you have a specific reason why you need/want to mount your disks via a script (and using sudo)...you should be able to mount with device notifier widget. You can also allow users to mount disks (without using sudo).

If I click on it to run it, it doesn't run.

Are you sure it doesn't run...or does it just not do what it is supposed to do?
To check whether your script runs at all, add a line at a start of your script:

Code:

echo $(date) >> ~/my_script_ran

This will write the time into a file (which will be created if it doesn't exist) in your home directory (/home/michelle/my_script_ran). The file either confirms the script was executed (the file was created and there is something wrong with the script) or not (the file was not created and there is problem trying to execute the script from GUI).

If I create a link to it, nothing happens when I try and use the link

Can you post the contents of the link .desktop file (it's a text file you can open with kate or another text editor)

I made a test script and it ran fine when clicked on, and also ran when clicking on a link to it (so your problems should be solvable).

Re: Problem running script from GUI

Hi Kubicle,

The reason for running the script is because some commercial DVDs aren't mounting properly automatically. Whey they mount, they have user and group ID's that are in the tens of thousands, and I can't access them properly. This isn't happening with older DVDs but some of the recent DVD's like Sanctuary and Family Guy series 7 and 8.

In order to get at them, I have to unmount and remount them. Hence the script.

When I run the script from the command line, the script takes a few moments to run. When I try with the terminal option enabled, I'm assuming that the result is the same ... ie. the error message.

I'm at work at present, but when I get home in a few hours, I'll post the contents of the link. Good to hear there is a likely solution!

Michelle.

Re: Problem running script from GUI

Here it is...

[Desktop Entry]
Comment[en_GB]=DVD mount change
Comment=DVD mount change
Exec=~/CD-mount.sh
GenericName[en_GB]=DVD mount change
GenericName=DVD mount change
Icon=exec
MimeType=
Name[en_GB]=DVD mount change
Name=DVD mount change
Path=
StartupNotify=false
Terminal=true
TerminalOptions=
Type=Application
X-DBUS-ServiceName=
X-DBUS-StartupType=none
X-KDE-SubstituteUID=true
X-KDE-Username=michelle
X-Ubuntu-Gettext-Domain=desktop_kdebase

...like I said, if the username is blank it brings up the error message. If it has a user name in it, it asks for the password and then runs the script.

Re: Problem running script from GUI

Did you try using a fully qualified path instead of

Code:

Exec=~/CD-mount.sh

**msknight** · Nov 06, 2009, 01:52 PM

Re: Problem running script from GUI

Yep, just tried it. Same error message in the terminal window (with no username given)

**vinnywright** · Nov 06, 2009, 02:31 PM

Re: Problem running script from GUI

what happens if you add to

path=
path=/home/michelle/CD-mount.sh

and

Exec=~/CD-mount.sh
to
Exec=CD-mount.sh

?

Re: Problem running script from GUI

The error changes to -

Warning: Could not find 'CD-mount.sh', starting '/bin/bash' instead. Please check your profile settings.

Re: Problem running script from GUI

Does the first line of your script contain a comment containing the program name to execute the script?

Code:

#!/bin/sh

**vinnywright** · Nov 06, 2009, 03:10 PM

Re: Problem running script from GUI

and is CD-mount.sh

in /home/michelle ?
