Bir Mac

Question

'daki terminaldeki çeşitli sistem değişkenlerinin değerlerini bir Mac'tayım. Terminalde, aşağıdaki değerlerin her birini nasıl anlayacaksınız?

• Kelime boyutu (64 bit vs 32 bit)
• L1/L2 önbellek boyutu

teşekkür (gibi df fakat RAM için) kullanılıyor ne kadar bellek belirleyin

! Bunları Activity Monitor, System Profiler vs.'de bulabileceğinizi biliyorum, ancak terminal ve UNIX hakkındaki bilgimi artırmaya çalışıyorum.

System Profiler, /usr/sbin/system_profiler civarında bir GUI paketleyicisidir.
