linux怎么查看cpu的信息
怎么看电脑cpu信息,以及判断cpu的性能,查看cpu的方法有很多,并且非常的简单,但还是有很多新手不知道怎么做,为此学习啦小编为大家整理推荐了相关的知识,希望大家喜欢。
linux查看cpu的信息的方法
1 查看CPU
1.1 查看CPU个数
# cat /proc/cpuinfo | grep "physical id" | 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 "cpu cores" | uniq
cpu cores : 4
1.3 查看CPU型号
# cat /proc/cpuinfo | grep 'model name' |uniq
model name : Intel(R) Xeon(R) CPU E5630 @ 2.53GHz
总结:该服务器有2个4核CPU,型号Intel(R) Xeon(R) CPU E5630 @ 2.53GHz
2 查看内存
2.1 查看内存总数
#cat /proc/meminfo | grep MemTotal
MemTotal: 32941268 kB //内存32G
2.2 查看内存条数
