linux下查看内存条数及每根内存大小的实现方法(推荐)

在linux系统中，查看内存条个数，及每根内存的大小，可以使用dmidecode命令。

如下：

#dmidecode | grep -a16 "memory device$"

输出结果：

memory device #存储设备
array handle: 0x1000 #阵列处理
error information handle: not provided #错误信息的处理：不提供 
total width: 72 bits #总宽度： 72位
data width: 64 bits #数据宽度： 64位 
size: 1024 mb #大小
form factor: 
set: 1
locator: dimm1 
bank locator: not specified
type: 
type detail: synchronous #输入详细信息：同步 
speed: 667 mhz (1.5 ns) #速度： 667兆赫（ 1.5纳秒）

serial number: 42600700 #序号
asset tag: 010910

然后，用free命令查看当前内存的使用情况：

# free -m 
total used free shared buffers cached
mem: 4054 2963 1090 0 144 1272
-/+ buffers/cache: 1547 2506
swap: 4094 0 4094
