 +===== Arbeitsspeicher =====
 +
 +  * [[Die Größe des realen Arbeitsspeicher ermitteln]]
 +
 +==== Plattenspeicher ====
 +
 +Die folgende Lösung ist die einfachste, aber leider Sprach- und Distributionsabhängig:
 +  fdisk -l | egrep ^'Platte /|Disk /'
 +  Disk /dev/sda: 72.7 GB, 72746008576 bytes
 +  Disk /dev/sdb: 898.9 GB, 898990342144 bytes
 +  Disk /dev/sdc: 1023 MB, 1023934464 bytes
 +
 +Das Laufwerk ///dev/sdc// ist ein 1GB-USB-Stick. Bei dieser Methode kann man ihn nicht klar genug von den eingebauten Laufwerken unterscheiden, deshalb ist eine der nachfolgenden Methoden zum ermitteln der internen Festplatten besser geeignet.
 +
 +Hier eine Distributionsunabhängige möglichkeit die Plattengröße zu ermitteln:
 +  fgrep -H 0 /sys/class/block/*/removable | egrep -v 'loop|ram|dm-' | awk -F'/' '{print $5}' | while read DEV;do echo "${DEV}=$(cat /sys/class/block/${DEV}/size) Bloecke";done
 +  sda=142082048 Bloecke
 +  sdb=1755840512 Bloecke
 +
 +oder in MB
 +  fgrep -H 0 /sys/class/block/*/removable | egrep -v 'loop|ram|dm-' | awk -F'/' '{print $5}' | while read DEV;do echo "${DEV}=$(cat /sys/class/block/${DEV}/size | awk -F'/' '{print $1/2048}') MB";done

 +Wenn man die Linuxemulation aktiviert hat und das Linux-//proc//-Verzeichnis gemountet hat, kann man es genauso wie bei Linux machen.

 +
 +Zur Erkennung der CPU, hat jede ein entsprechendes Flag:
 +
 +  - Real mode - 16 bit CPU
 +  - i286-Protected Mode - 16-bit CPU
 +  - i386-Protected Mode - 32-bit CPU
 +  - Long mode (lm) - 64 bit CPU
 +
 +Die 64-Bit-CPUs haben das Flag //lm// (//long mode//):
 +
 +  egrep ^flags /proc/cpuinfo | tr -s ' ' '\n' | egrep ^lm | uniq
 +  lm
 +
 +
 +==== Hardware-Virtualisierung ====
 +
 +  egrep ^flags /proc/cpuinfo | tr -s ' ' '\n' | egrep 'vmx|svm' | uniq
 +  vmx
 +
 +oder
 +
 +  egrep 'vmx|svm' /proc/cpuinfo > /dev/null && echo "CPU unterstützt Hardware-Virtualisierung" || echo "CPU unterstützt keine Hardware-Virtualisierung"
 +  CPU unterstützt Hardware-Virtualisierung
 +
 +===== MAC-Adressen =====
 +
 +So ermittelt man die MAC-Adressen eines Linux-Systems am Sinnvollsten und umgeht dadurch einige Fallstricke, die durch Systemunterschiede auftreten.
 +
 +  find /sys/ -type f | egrep 'address' | fgrep -i 'eth' | xargs cat ${1}
