查看系统的内存

查看cpu个数,核心数,型号,频率

实际cpu个数:  cat /proc/cpuinfo | grep ‘physical id’ | uniq -c
4 physical id     : 0       4 physical id     : 1       4 physical id     : 0       4 physical id     : 1

实际cpu核心数及型号频率

[root@puppet124 ~]# cat /proc/cpuinfo | grep name | cut -d: -f2 | uniq -c      16  Intel(R) Xeon(R) CPU           L5520  @ 2.27GHz

查看内存条数及大小

dmidecode | grep -P -A 5 “Memory Device” | grep Size | grep -v Range | grep -v No

查看物理网卡及MAC地址

ifconfig -a | grep HWaddr | awk ‘{print $5}’

查看网卡支持的速度及当前工作的状态

# ethtool eth0

脚本:
cpu and Mem:

cpu物理个数

physical cpu count: `cat /proc/cpuinfo | grep ‘physical id’ | uniq -c | wc -l`

cpu核心个数型号频率

processor core count: `cat /proc/cpuinfo | grep name | cut -d: -f2 | uniq -c | awk ‘{print $1}’`
processor model: `cat /proc/cpuinfo | grep name | cut -d’:’ -f 2 | uniq`

memory sock count:`dmidecode | grep -P -A 5 “Memory Device” | grep Size | grep -v Range`
total memory:`dmidecode | grep -P -A 5 “Memory Device” | grep “Range Size”`
