Linux下查看CPU信息以及系统信息

先说说如何查看CPU的详细信息:

txi@ghosTunix:~$
cat /proc/cpuinfo

processor     : 0

vendor_id     : GenuineIntel

cpu family     : 6

bogomips     : 3990.07

clflush size     : 64

      可以看到，/proc/cpuinfo文件记录了CPU的详细信息

，查看CPU温度的方法：

txi@ghosTunix:~$ cat /proc/acpi/thermal_zone/TZS0/temperature

temperature:              34 C

txi@ghosTunix:~$ cat /proc/acpi/thermal_zone/TZS1/temperature

temperature:              37 C

      在查询CPU信息的同时，我了解到了一个非常优秀的查看BIOS信息的工具dmidecode

：

root@ghosTunix:/home/txi#
dmidecode

# dmidecode 2.9

SMBIOS 2.4 present.
