Linux 学习笔记（三）- 查看Linux版本系统信息方法汇总

Linux下如何查看版本信息， 包括位数、版本信息以及CPU内核信息、CPU具体型号等等，整个CPU信息一目了然。
　　1、# uname －a （Linux查看版本当前操作系统内核信息）
　　Linux localhost.localdomain 2.4.20-8 #1 Thu Mar 13 17:54:28 EST 2003 i686 athlon i386 GNU/Linux
　　2、# cat /proc/version （Linux查看当前操作系统版本信息）
Linux version 2.4.20-8 (bhcompile@porky.devel.redhat.com)
(gcc version 3.2.2 20030222 (Red Hat Linux 3.2.2-5)) #1 Thu Mar 13 17:54:28 EST 2003
　　3、# cat /etc/issue 或cat /etc/redhat-release（Linux查看版本当前操作系统发行版信息）
　　Red Hat Linux release 9 (Shrike)

　　4、# cat /proc/cpuinfo （Linux查看cpu相关信息，包括型号、主频、内核信息等）

uname -a ：显示系统名、节点名称、操作系统的发行版号、操作系统版本、运行系统的机器 ID 号

Print certain system information. With no OPTION, same as -s.
-a, --all print all information, in the following order,
except omit -p and -i if unknown:
-s, --kernel-name print the kernel name
-n, --nodename print the network node hostname
-r, --kernel-release print the kernel release
-v, --kernel-version print the kernel version
-m, --machine print the machine hardware name
-p, --processor print the processor type or "unknown"
-i, --hardware-platform print the hardware platform or "unknown"
-o, --operating-system print the operating system
--help display this help and exit
--version output version information and exit
