Linux command to find cpu processor speed

Here’s an easy shell command to get info about a computer’s cpu:
cat /proc/cpuinfo
It should give you some output like this:

Typical output from cat /proc/cpuinfo

Typical output from cat /proc/cpuinfo

From the output in the image above, we can see that the cpu is an 800 mhz Pentium III, with a 256k cache.  This command should work on nearly any standard Linux system, whether it’s Ubuntu, Suse, or just about any other flavor.
