Dio Aio Cover Dmg If Leak

Hi, very new to Terminal commands and need a little help executing one. I'm trying to dual boot Ubuntu on my MacBook Pro using a USB device to start the initial boot / installation from. And here's where I got to on the ubuntu website:
'Convert the .iso file to .img using the convert option of hdiutil (e.g., hdiutil convert -format UDRW -o ~/path/to/target.img ~/path/to/ubuntu.iso)'
I'm in Terminal but I'm really not sure what parts of that command to change and what parts to leave alone. I've tried various google searches and variations but I just keep getting errors. Would someone be kind enough to either give me the complete moron's guide to executing this particular command or simply direct me to a free program that converts .iso to .img. I would much prefer a program to do it for me, as I don't want to risk screwing it up. Thanks in advance for help / assistance.

Modded DMG's
So I had some left over DMG parts and wanted to mod them. Anyways, see below for a few pics.
1st one I did
New yellow shell with black glass and blue buttons with LEDs

2nd one
White shell and teal buttons (no LEDs this time), grey glass
Teal backlight and bivert
3rd one
Black shell, blue glass, blue buttons, white backlight
4th one
Black shell with white buttons and screen cover. Teal backlight.
5th one
This was a custom painted gold shell that I got a hold of for cheap, a black glass screen cover and black buttons. I did not have a bivert chip handy so this one just got a backlight. It turned out okay, but the bivert would have made it much better:
6th one
This is one of my favorites, a OEM clear PIL. I used a green backlight and bivert, and had some silicone buttons as well. Turned out amazing I think.
7th one

Again, another great one. This was using an OEM PIL green shell. I used the original grey buttons and added a new grey glass lens. Installed a yellow backlight and bivert.
I have also since done a few pockets too. A little bit more of a pain to work with and the AAA's don't seem to like to power a backlight that much either. But they still look nice.
1st pocket
Used an aftermarket clear blue shell with white buttons, and a yellow backlight. No bivert on this one.
2nd pocket

Used an aftermarket DMG themed shell on this guy. and a white backlight with a bivert this time. i'll likely mod this one with a lipo battery since I still have it on hand, and it will help with powering the backlight.
