1、Linux下如何查看CPU信息,包括位数和多核信息查看当前操作系统内核信息#uname-aLinuxredcat2.6.31-20-generic#58-UbuntuSMPFriMar1205:23:09UTC2010i686GNU/Linux查看当前操作系统发行版信息#cat/etc/issueUbuntu9.10l查看cpu型号#cat/proc/cpuinfo

2、grepname

3、cut-f2-d:

4、uniq-c2Intel(R)Core(TM)2DuoCPUP8600@2.40GHz(看到有2个逻辑CPU,也知道了CPU型号)查看物理cpu颗数#cat/proc/cpuinf

5、o

6、grepphysical

7、uniq-c2physicalid:0(说明实际上是1颗2核的CPU)查看cpu运行模式#getconfLONG_BIT32(说明当前CPU运行在32bit模式下,但不代表CPU不支持64bit)查看cpu是否支持64bit#cat/proc/cpuinfo

8、grepflags

9、grep'lm'

10、wc-l2(结果大于0,说明支持64bit计算.lm指longmode,支持lm则是64bit)查看cpu信息概要（昨天看aix的时候刚发现的，在ubuntu上竟然也有~）：#lscpuArchitecture:i686#架构686CPU(s):2#逻辑cpu颗数是
