Linux下查看cpu核数的命令

1、几个cpu

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

2、每个cpu是几核（假设cpu配置相同）

# more /proc/cpuinfo |grep "physical id"|grep "0"|wc -l
# cat /proc/cpuinfo | grep processor

3、查看物理CPU的个数

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

4、查看逻辑CPU的个数

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

5、查看CPU是几核

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

6、查看CPU的主频

# cat /proc/cpuinfo |grep MHz|uniq
