How to get the codename for the processor in Linux?

Hi Folks,

When I want find the CPU config i get all information from /proc/cpuinfo. Only one thing I am missing is finding the codename of the processor. From windows i use a tool which gives me this. Example codenames are Prestonia, Foster etc etc.

I don't know which distro you're using, but Debian (or derivatives) offer lshw and hwinfo, available in the repositories. Extremely informative (using those tools with the -short/--short option is more than enough in most cases).

If you want to use a live CD: grml comes with a full set of the tools mentionned (and more).

cpuid gives a good deal more info about the CPU itself than does lshw (one of my favorite tools). but it still doesn't appear to provide the codenames.
