檢視cpu型號
cat /proc/cpuinfo | grep name | cut -f2 -d: | uniq -c
16 intel(r) xeon(r) cpu x5560 @ 2.80ghz
檢視物理cpu個數
cat /proc/cpuinfo | grep physical | uniq -c
1 physical id : 1
1 physical id : 0
檢視cpu執行模式：32位或者64位，如果是32位的話並不代表不能執行在64位下
getconf long_bit
64檢視是否cpu支援64位系統，如果值大於0，則支援64位運算，lm指long mode
cat /proc/cpuinfo | grep flags | grep ' lm ' | wc -l 16
檢視記憶體資訊
cat /proc/meminfo
