Linux查看CPU,内存,硬盘命令

1查看CPU

1.1查看CPU个数
#cat/proc/cpuinfo|grep“physicalid“|uniq|wc-l
2
**uniq命令：删除重复行；wc–l命令：统计行数**

1.2查看CPU核数
#cat/proc/cpuinfo|grep“cpucores“|uniq
cpucores:4

1.3查看CPU型号
#cat/proc/cpuinfo|grep'modelname'|uniq
modelname:Intel(R)Xeon(R)CPUE5630@2.53GHz

总结：该服务器有2个4核CPU，型号Intel(R)Xeon(R)CPUE5630@2.53GHz

2查看内存

2.1查看内存总数
#cat/proc/meminfo|grepMemTotal
MemTotal:32941268kB//内存32G

2.2查看内存条数
