Cat command confusion.


Hi,

I think i've dl all the files (and md5sum ed them) to compile a Centos dvd, but i need to 'cat' them in right order before i burn to disc. Could some one give me the command, and perhaps explain it ?

Thanks for your interest,

Hello Mr.

How can we cat the iso image file? It's not possible. I din listen about this issue. but we can mount iso image at a point directory..
if u wud find the solution then please tell me..

but I think it's not possible..
u can check with md5sum . its easy . whts a problem?
md5sum is best method to check larger files that is correct or not..

thanks

The ISO's are probably CD ISO images.

Burn them to disk and access them from there or mount them as follows

mount -o loop /path/to/my.iso /path/to/mount/point

The Xof7 images are CD images.

There is a DVD torrent in there (what I know contains 2 DVD images) and a live CD... what is it you are actually after? If you are after the DVD images, this is what the torrents are for. Else wise nothing else here is actually meant for the DVD... almost all the CentOS mirrors are the same to this, only supplying a torrent (tho I know of one or two that have the 1st DVD as a directly down-loadable file)

I doubt you are supposed to cat them together. Usually when a distro comes in multiple ISOs you should burn each one to a separate disc, insert the first one, and put in others when instructed.

I understood that to mean "I need to take the CD images and form a DVD image out of them". See the link I posted earlier; it says on the page

Code:
The following script (mkdvdiso.sh) has been tested for CentOS 4 and 5 i386 to create DVD ISO images from CD images, or from an installation tree. If the installation tree does not contain a .discinfo file, one must be obtained from the top level of a CD.
which seems to do just that. A better option might have been to download the DVD image in the first place, but if the CD images are already there and here's a script that turns them into a DVD, why not? Depending on internet connection speed and the computer hardware, it might be faster than downloading the enormous DVD image...
