I've written a simple script to mount and un-mount ISO image.
if /bin/mount|grep $1; then
/usr/bin/sudo /bin/umount $1
/usr/bin/sudo /bin/mount $1 /media/ISO_MountPoint/
Then I associated it with *.ISO files, so that I can mount/un-mount an ISO image by simply double clicking it, instead of typing command.
It works but there's a little unsatisfactory thing: The interface that let me input root password is Konsole. How can I change the interface to KDE-SU as shown in the picture?
Any suggestions are appreciated!
