# 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
