Our next script file today allows you to mount any ISO image on your PC to any folder, read only, so you may browse or copy the contents of that ISO file. Now consider that this script is being placed here as an inspiration to creating script files of your own. The fact that it might do something useful in addition, is just a plus. The meat of this script is the command: mount -o loop -t iso9660 name_of_iso_file folder_to_mount_to. So, you can bypass the script and use this command if you wish.
However, this script will check to make sure your ISO file exists, that the target folder exists, it will request a root user password and provide an error code should something go wrong. In order to create this script, copy and past the text in the following code section and save it as the text file mountiso in your home area bin folder (~/bin).

# End Of Script
To make the script file executable, run the following terminal command:
chmod +x ~/bin/mount
As an example, suppose we downloaded the 64 bit openSUSE DVD and we wanted to look at its contents without making a new DVD. Normally, downloaded files go to your home Downloads folder. Further, if you look at your openSUSE folder system, you will see a normally unused folder called /mnt (it is normally unused, but look first with a File Manager to make sure). Let us suppose we enter the following command using mountiso:
mountiso ~/Downloads/openSUSE-11.3-DVD-x86_64.iso /mnt
Here is the resulting output from that iso file mount using mountiso.
mountiso - Mount any ISO file, intended to make a CD or DVD, as a disk drive
mount: warning: /mnt seems to be mounted read-only.

If you have any comments or suggestions for mountiso, please let me hear what they are.
Thank You,
