linux 下檢視機器是cpu是幾核的

幾個cpu

more /proc/cpuinfo |grep 「physical id」|uniq|wc -l

每個cpu是幾核（假設cpu配置相同）

more /proc/cpuinfo |grep 「physical id」|grep 「0」|wc -l

cat /proc/cpuinfo | grep processor

檢視物理cpu的個數

# cat /proc/cpuinfo |grep "physical id"|sort |uniq|wc -l

# cat /proc/cpuinfo |grep "processor"|wc -l

# cat /proc/cpuinfo |grep "cores"|uniq

# cat /proc/cpuinfo |grep mhz|uniq

# uname -a

linux euis1 2.6.9-55.elsmp #1 smp fri apr 20 17:03:35 edt 2007 i686 i686 i386 gnu/linux

# cat /etc/issue | grep linux

(檢視當前作業系統發行版資訊)

# cat /proc/cpuinfo | grep name | cut -f2 -d: | uniq -c

8  intel(r) xeon(r) cpu            e5410   @ 2.33ghz

# cat /proc/cpuinfo | grep physical | uniq -c

4 physical id      : 0

4 physical id : 1

# getconf long_bit

# cat /proc/cpuinfo | grep flags | grep ' lm ' | wc -l

如何獲得cpu的詳細資訊：

linux命令：cat /proc/cpuinfo

用命令判斷幾個物理cpu，幾個核等：

邏輯cpu個數：

# cat /proc/cpuinfo | grep "processor" | wc -l

# cat /proc/cpuinfo | grep "physical id" | sort | uniq | wc -l

# cat /proc/cpuinfo | grep "cpu cores" | wc -l

如果有兩個邏輯cpu具有相同的」core id」，那麼超執行緒是開啟的。

每個物理cpu中邏輯cpu(可能是core, threads或both)的個數：

# cat /proc/cpuinfo | grep "siblings"
