sysctl -a

[ogino (1668)]

machdep.cpu とか覚えられないので、いつも sysctl -a | grep cpu です。
hw の下にも、hw.physicalcpu とか hw.logicalcpu とかあるみたいです。

Re:sysctl -a

[SlippingStaff (46608)]

grep してこれでっか…。`man sysctl` (§8) したけど、各エントリを追う気にはなれないですナ。

CPU 機能のエントリは一部（廉価版 68k で "FPU" は出ないねとかその程度）を除いて意味が分からないのもあって、変な笑いが出ました。
そんなコレデモカと並べられてもー みたいな。

❯ sysctl -a | grep 'cpu.*features'

同じ「i5」でもこちらは色々と少ない。
