An ISO file is a file, you can use all manner of Unix tools such as cat to read it. You should elaborate more about your intention in order to getting better help. – Chen Levy Aug 4 '10 at 8:25
What do you mean byte by byte? What are you trying to do? – Matthew Flaschen Aug 4 '10 at 8:40
I think he is trying to extract one file from ISO and read it. Ugur, am I correct? – netme Aug 4 '10 at 8:43
I just want to read first bit of the iso. is it 1 or 0? I just need that. – ugur Aug 4 '10 at 8:56
What language are you using? – Mark Aug 4 '10 at 9:07

cat and read is OK.
You can do sth. like:
cat file.iso | while read -n 1 x ; do .. here do something with one character (like echo "$x") .. ; done
for more info use: man cat help read help while
Or you can use C man 2 read

An ISO is just a container file, much like a zip file. Most compression utilities (such as 7-zip for windows) can extract the files contained in the ISO to your hard drive for you.
