Rox Desktop Icons on a JWM window manager auto mounting a icon for a text editor? Or auto mounting a icon period for a cd disk inserted and running?

Then it should mount OK this must be a puppy linux thing, which I can't help you with, its probably just a permissions thing, you may need to add yourself to a specific group to be able to mount cdroms eg group 'cdrom'.
Try mounting it manually and see what happens.
Puppy is a single user system by default and runs as root unless spot or fido is used to launch applications as a user.
Non of that maybe applies in this thread as nothing mentioned as running as user spot or fido.

This works.

But how can I have a script check for 'no disk' and perform an action based on that info ?

no disc

Something like

Code:
  cd_chk=$( cddetect_quick -d /dev/sr0 )
  if [[ $cd_chk == "no disc" ]]; then
    do something here
  fi

Thanks.

This works except for the thunar line.

The CD drive is mounted but no files are shown in /mnt/sr0.

cd_chk=$( cddetect_quick -d /dev/sr0 )

if [[ $cd_chk == "no disc" ]]; then
echo "No CD/DVD in drive !!"
exit
fi

if [[ $cd_chk == "disc inserted" ]]; then
echo "CD/DVD is in drive."
thunar /mnt/sr0/
fi

Not sure I understand, thunar is not opening a new window /mnt/sr0 or it is and your not seeing any files?

According to the man page the URI is specified with file: i.e.

thunar file:/mnt/sr0

I tried thunar file:/mnt/sr0 and it also did not show any files.

I will see if Rox Filer command will show the files.

rox /mnt/sr0/ does not show any files either.

Are you sure the disc is mounted?
