LinuxやFreeBSDでCPUやメモリの情報を調べる

LinuxとFreeBSDでCPU情報とかの取得を良く忘れてしまうのでメモ。特にFreeBSDは/var/log/dmesg.todayでしか見れないと昔思っていたので、しょっちゅう忘れてしまう。

Linuxの場合

/procディレクトリの下にあるファイルに一通り入っている。CPUの場合はcpuinfoを見ればよい

% cat /proc/cpuinfo
processor       : 0
vendor_id       : GenuineIntel
cpu family      : 15
model           : 4

stepping        : 3
cpu MHz         : 3000.422

hlt_bug         : no
f00f_bug        : no
coma_bug        : no
fpu             : yes
fpu_exception   : yes
cpuid level     : 5
wp              : yes

bogomips        : 6003.37

メモリの場合はmeminfo
