【Linux常用命令】系统信息(内核,Linux版本)

本文介绍了如何在Linux系统中查看内核版本及系统版本的方法。针对内核版本提供了两种命令方式,分别为cat /proc/version和uname -a。对于系统版本查询,则提供了四种不同的命令:lsb_release -a、cat /etc/redhat-release、cat /etc/centos-release以及cat /etc/issue。这些命令适用于多种Linux发行版。

一、查看Linux内核版本命令(2种方法):

1、cat /proc/version

[root@S-CentOS home]# cat /proc/version

2、uname -a

[root@S-CentOS home]# uname -a

Linux S-CentOS 2.6.32-431.el6.x86_64 #1 SMP Fri Nov 22 03:15:09 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

二、查看Linux系统版本的命令(3种方法):

1、lsb_release -a,即可列出所有版本信息,这个命令适用于所有的Linux发行版,包括RedHat、SUSE、Debian…等发行版。

[root@S-CentOS ~]# lsb_release -a

Distributor ID: CentOS

Description: CentOS release 6.5 (Final)

Codename: Final

2、cat /etc/redhat-release,这个命令只适合Redhat系的Linux。

[root@S-CentOS home]# cat /etc/redhat-release

3、cat /etc/centos-release,这个命令只适合Centos系的Linux。

[root@S-CentOS home]# cat /etc/redhat-release
