Tiny Deathstars of Foulness

The hostinfo command displays information about your host; namely your kernel version, the number of processors the kernel is configured for, the number of physical processors active, the number of logical processors active, the type of those processors, which ones are active, the amount of memory available, tasks, threads, and average load. Run hosting without any arguments or options: hostinfo The output would be as follows (ymmv per system): Mach kernel version: Darwin Kernel Version 15.0.0: Wed Aug 26 19:41:34 PDT 2015; root:xnu-3247.1.106~5/RELEASE_X86_64 Kernel configured for up to 4 processors. 2 processors are physically available. 4 processors are logically available. Processor type: x86_64h (Intel x86-64h Haswell) Processors active: 0 1 2 3 Primary memory available: 16.00 gigabytes Default processor set: 395 tasks, 1711 threads, 4 processors Load average: 1.78, Mach factor: 2.21 There are a bunch of other commands that can provide far more detailed information about your system. However, hostinfo has remained basically unchanged for 13 years, so if I can get something there, I can trust it’s fairly future-proofed in my scripts.
