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
