I'm in a real hurry so I thought there is a way to do that but I don't know how. I thought about piping wget -c cdimage.ubuntu.com/daily-live/current/utopic-desktop-amd64.iso | BurningApp but I don't know how either.

I usually use Unetbootin to "burn" it to a USB Flash Storage Device.Currently I'm running Lubuntu 14.04/10.

Please note I want to burn it to a USB Flash Storage Device.

I wonder if it's really possible. At least, you would have to give to the burner some extra information, like the total size of the .iso file, before it can start burning. – lgeorget Jul 8 '14 at 9:07
@lgeorget: Why would it need that? Back in the day it used to be the way to go to mkisofs ... | cdrecord .... If that information is really required it's probably in the meta information of the iso-image. I have forgotten most of it, but appart from buffer underrun problems, which also should be a thing of the past, I do not see why wget -O - http://path.to/image.iso | cdrecord ... should not work. I'm just not posting an answer because I don't recall which parameters cdrecord needs, let alone what's sensible for the problem at hand. – Bananguin Jul 8 '14 at 9:54

@NatusVincere: Could you please elaborate on the process of burning onto USB flash disks? I am not familiar with this. What does it accomplish? – Bananguin Jul 8 '14 at 9:57
if you want to transfer the iso (as is) without partitioning the usb drive you can use dd to acomplish that. Have in mind that you will loose space from the usb since you are not partitioning it and the only partition after the process will be the one contained in the iso. – YoMismo Jul 8 '14 at 10:32

Example using wget (for downloading), bfr (for buffering), and growisofs for burning:

wget -q -O - http://somewhere/image.iso \
| bfr -b 512m -p -i 100% -m 10% -t 120 -T 95% \
| growisofs -dvd-compat -Z /dev/cdrom=/dev/fd/0

The buffering part is optional, but without it you will have to rely on your drive to cope with buffer underruns. That doesn't work too well if you have underruns all the time, so your Internet connection better be faster than your drive...

D'oh, completely missed the USB flash part. That's not burning in my book :I

wget -q -O - http://somewhere/image.iso > /dev/usbstick

or even just

wget -O /dev/usbstick http://somewhere/image.iso
