Bu yazıda sizlere Linux’da CPU ile ilgili bütün detayları inceleyebileceğimiz komutları göstereceğim. Aşağıdaki komutlar da bu konuda bize yardımcı olacak.
Kullanacağımız ilk yöntem
/proc/cpuinfo; işlemci detaylarını en rahat ve basit şekilde görütüleyebileceğiniz dosyadır. Grep kullanarak sadece ayrıntılarıda listeyebilirsiniz. (Sadece ayrıntıları görebileceğiniz parametreler aşağıdadır.)
