Is there any command on linux to check if CD or DVD is 32bit or 64bit?

    What do you mean by "32 bit" and "64 bit" in this context?

A CD or DVD is not really 32 bits or 64 bits. However, it may contain a 64 bit program. The linux utility file can tell you more about an executable.


if you have a live distro running you can check the running version with uname -a
