linux查看内存的生产商,linux下查看CPU.内存型号.pci 转自《Ivan-blog》
cat /proc/cpuinfo | grep 'physical id'
physical id : 0
physical id : 0
physical id : 0
physical id : 0
如果physical id相同，表示这是一颗4核心的CPU
查看CPU的生产商和型号:
查看生产商：
cat /proc/cpuinfo | grep ‘vendor_id’
查看型号：
cat /proc/cpuinfo | grep ‘model name’
查看频率：
cat /proc/cpuinfo | grep ‘cpu MHz’
查看核心的数量：
cat /proc/cpuinfo | grep ‘cpu cores’
free -m
total used free shared buffers cached
Mem: 4048 1708 2339 0 164 1464
-/+ buffers/cache: 80 3967
Swap: 1983 0 1983
说明： -m参数，以M字节(megabytes)为单位查看内存大小，
上面的例子中我们可以看到，内存的总大小是4048M，也就是4G

从上面我们可以看到有4条1G的内存被安装在前4条内存插槽上，而locator从DIMM5－DIMM8是空着的
前四条内存的型号为：Part Number: NT1GT72U8PB1BN-3C
生产商的ID是：Manufacturer: 830B8089830B
1，查看pci的相关信息
先解释一下概念：
什么是PCI
Peripheral Component Interconnect，外围设备互联，
它是计算机上面应用的设备总线(总线，就是bus,是传输数据信号的通道)
lspci
这个命令默认是已经安装的，
如找不到此命令，可以安装pciutils这个包
命令举例:
lspci

从中看到的信息：Ethernet controller：这个是网卡
VGA compatible controller：这个是显卡
USB Controller： USB控制器
SCSI storage controller： SCSI的存储控制器
说明：如果你感觉这份信息还不够详细，
那么可以在后面添加参数，有3个参数可以使用：
lspci -v verbose 详细
lspci -vv very verbose 很详细
lspci -vvv even more verbose 更详细
以树结构来显示pci总线：
lspci -tv
简单显示：
