uname -m and uname -p

[Kaushal Shriyan]

Hi

when i do the below command, I get the below information

$ uname -m
x86_64
$ uname -p
unknown
$

whats the difference between the two command and i have referred to man uname
which says

       -m, --machine
              print the machine hardware name

       -p, --processor
              print the processor type or "unknown"

But could not understand,

Thanks and Regards

Kaushal
