To get the count of physical CPUs, this works by counting the unique physical ids
grep “physical id” /proc/cpuinfo |sort -u|wc -l

Well… Sorry to say that it doesn’t work most of the time. Beside multithreadin processors, It is common that entry on a single processor has multiple occurence of word “processor” (both in the procesor identifier and model name.
On my ancient pemtium M laptop it reports 2 processors because ist modelname is “Intel(R) Pentium(R) M processor 1.73GHz”.

This might help:
grep -c ^processor /proc/cpuinfo

Won’t this count CPUs with hyperthreading twice? My computer has one Pentium 4 (Prescott) CPU, but has two processor entries in cpuinfo.

This will save you a pipe
grep -c processor /proc/cpuinfo

Hi,
this will give you the same result and saves you having to type a couple of characters

grep processor /proc/cpuinfo |wc -l
