lscpu

lscpu for BSDs. The main usage of this program should be for x86 architecture since it leverages CPUID instructions. For other architectures, it just shows very limited facts.

lscpu has been verified to work on following BSDs:

macOS	OpenBSD	FreeBSD	NetBSD
DragonFlyBSD	MidnightBSD	TrueOS	?

It should also work on other BSDs, though not tested. If you find lscpu also runs on other BSDs, please tell me by mail or just open a new issue, thanks very much in advance!

Usage

$ git clone https://github.com/NanXiao/lscpu.git
$ cd lscpu
$ make
$ ./lscpu
