linux查看硬件信息

Posted 2020-11-22

linux 测试机器的硬件信息：?

查看CPU信息（型号）?

cat /proc/cpuinfo | grep name | cut -f2 -d: | uniq -c?
8? Intel(R) Xeon(R) CPU??????????? E5410?? @ 2.33GHz?

(看到有8个逻辑CPU, 也知道了CPU型号)?

cat /proc/cpuinfo | grep physical | uniq -c?
4 physical id????? : 0?
4 physical id????? : 1?

(说明实际上是两颗4核的CPU)?

getconf LONG_BIT?
32?

(说明当前CPU运行在32bit模式下, 但不代表CPU不支持64bit)?

 cat /proc/cpuinfo | grep flags | grep ‘ lm ‘ | wc -l?
8?

(结果大于0, 说明支持64bit计算. lm指long mode, 支持lm则是64bit)?

再完整看cpu详细信息, 不过大部分我们都不关心而已.?
dmidecode | grep ‘Processor Information‘?

查看内 存信息?

 cat /proc/meminfo?

 uname -a?
Linux euis1 2.6.9-55.ELsmp #1 SMP Fri Apr 20 17:03:35 EDT 2007 i686 i686 i386 GNU/Linux?

(查看当前操作系统内核信息)?

 cat /etc/issue | grep Linux?
Red Hat Enterprise Linux AS release 4 (Nahant Update 5)?

(查看当前操作系统发行版信息)?

查看机器型号?
dmidecode | grep "Product Name"??

查看网卡信息?
dmesg | grep -i eth
