mount-umount-iso

#!/bin/sh
#
# mount-unmount-iso is a nautilus script that mounts or unmounts an iso file
# with a right-click on the particular file. The default mount point is
# /media/iso/<filename> (folders will be created if they don't exist, yet).
# On Ubuntu Linux the mounted file will automatically show up
# this script
# ending with a tilde '~' recursively, starting in the marked
# folder. (e.g. right-click on a folder and all files/folders get removed)
# There is no undo function, so make sure you don't need the backups anymore.
