How do I download and burn a DVD ISO to a blank DVD directly?

Using Linux, how do I download a DVD ISO and burn it directly to a blank DVD in a DVD device in a single command without downloading it to hard drive or to RAM?

I am thinking of Gentoo 12 at 3.6 GB, and I do not have space on my Linux hard drive nor enough RAM to download to either.

Is there no net-install for Gentoo?

 

You can use wget | iso-burning command of your choice. But not sure if you'll manage to stream info fast enough for the software to burn the media without errors.

Hi noblelord,

I am not interested in installing Gentoo, just giving the DVD ISO a boot without installing.

Hi Mrk,

Yeah, I was thinking of something like that.

Think I'll try wget | cdrecord ...

Thanks,

Here is what did work with the least trouble: curl

When I tried to use wget <http address> | sudo dd of=/dev/sdX it insisted on saving the http ISO to a file instead of piping it to stdout, whereas curl had no trouble piping into the dd command with sudo to the device file of an 8GB USB flash drive. Disk Utility in Ubuntu 11.04 confirmed the detection of the ISO file on the flash drive.

I have not yet tried: curl <http addr> | sudo cdrecord .... - , but I suspect it too will work.

If you have an external device - your thumb drive - you can download to it through the browser

Hi Mrk,

I prefer using the command line method. Using FF 3.6.28, everytime I bring up Edit>Preferences, the Downloads tab does not always show and the last tab used previously seems to always be blanked out, however, I do get your gist,

via command like what i do

what ever drive you want to go to 1st mount if already mounted

give path to that drive

and from there run wget it will download at that place

example you put drive it auto mount or use mount command

$cd /

$ cd /media/drive name


edit: 1st time it give me 404 error i spider and check second time it working you dont need to put http://

i copy working link from my wget and putting below please check it. here its working hope it help

wget gentoo.mirrors.tds.net/pub/gentoo//releases/amd64/12.0/livedvd-amd64-multilib-2012.iso


as far burning i really dont know never tries i guess mrk suggest chaining 2 commands download + burning hope he put more light on it.

here i guess you need to put burn command instead of halt
