如何查看 LINUX 发行版的名称及其版本号

查看 Linux 内核版本命令( 两种方法 )

1. cat /proc/version

[root@localhost ~]# cat /proc/version
Linux version 2.6.18-194.8.1.el5.centos.plus
(mockbuild@builder17.centos.org) (gcc version 4.1.220080704
(Red Hat 4.1.2-48)) #1 SMP Wed Jul 7 11:50:45 EDT 2010

2. uname -a

[root@localhost ~]# uname -a
Linux localhost.localdomain 2.6.18-194.8.1.el5.centos.plus 
#1 SMP Wed Jul 7 11:50:45 EDT 2010 i686 i686 i386 GNU/Linux

查看 Linux 系统版本的命令

0. cat /etc/os-release

awk -F= '/^NAME/{print $2}' /etc/os-release | awk '{print $1}' | sed 's/\"//g' | tr [A-Z] [a-z]

1. lsb_release -a

[root@localhost ~]# lsb_release -a
LSB Version: :core-3.1-ia32:core-3.1-noarch:graphics-3.1-ia32:graphics-3.1-noarch
Distributor ID: CentOS
Description: CentOS release 6.5 (Final)
Release: 6.5
Codename: Final

这个命令适用于所有的Linux发行版, 包括 Redhat、SuSE、Debian…等发行版。

2. cat /etc/redhat-release，这种方法只适合Redhat系的Linux：

[root@localhost ~]# cat /etc/redhat-release
CentOS release 6.7 (Final)

3. cat /etc/issue，此命令也适用于所有的Linux发行版。

[root@localhost ~]# cat /etc/issue
CentOS release 6.7 (Final)
