（1）lsb_release 命令查看，FSG（Free Standards Group）组织开发的LSB (Linux Standard Base)标准的一个命令，用来查看linux兼容性的发行版信息
[root@enmoteam1 oracle]# lsb_release -h
FSG lsb_release v2.0 prints certain LSB (Linux Standard Base) and Distribution information. Usage: lsb_release [OPTION]... With no OPTION specified defaults to -v. Options: -v, --version Display the version of the LSB specification against which the distribution is compliant. -i, --id Display the string id of the distributor. -d, --description Display the single line text description of the distribution. -r, --release Display the release number of the distribution. -c, --codename Display the codename according to the distribution release. -a, --all Display all of the above information. -s, --short Use short output format for information requested by other options (or version if none). -h, --help Display this message. [root@enmoteam1 oracle]# lsb_release -v LSB Version: :core-4.0-amd64:core-4.0-noarch:graphics-4.0-amd64:graphics-4.0-noarch:printing-4.0-amd64:printing-4.0-noarch [root@enmoteam1 oracle]# lsb_release -i Distributor ID: RedHatEnterpriseServer [root@enmoteam1 oracle]# lsb_release -d Description: Red Hat Enterprise Linux Server release 6.3 (Santiago) [root@enmoteam1 oracle]# c -bash: c: command not found [root@enmoteam1 oracle]# lsb_release -c Codename: Santiago [root@enmoteam1 oracle]# lsb_release -a LSB Version: :core-4.0-amd64:core-4.0-noarch:graphics-4.0-amd64:graphics-4.0-noarch:printing-4.0-amd64:printing-4.0-noarch Distributor ID: RedHatEnterpriseServer Description: Red Hat Enterprise Linux Server release 6.3 (Santiago) Release: 6.3 Codename: Santiago [root@enmoteam1 oracle]# lsb_release -s :core-4.0-amd64:core-4.0-noarch:graphics-4.0-amd64:graphics-4.0-noarch:printing-4.0-amd64:printing-4.0-noarch[root@enmoteam1 oracle]#
（2）/etc/issue查看，是系统安装时默认的发行版本号信息。通常安装好系统后文件内容不会发生变化
[root@enmoteam1 oracle]# cat /etc/issue Oracle Linux Server release 6.3 Kernel \r on an \m [root@enmoteam1 oracle]#
(3)/proc/version 和 uname -a 显示的内容同样，显示linux内核版本。
[root@enmoteam1 oracle]# cat /proc/version Linux version 2.6.39-200.24.1.el6uek.x86_64 (mockbuild@ca-build44.us.oracle.com) (gcc version 4.4.6 20110731 (Red Hat 4.4.6-3) (GCC) ) #1 SMP Sat Jun 23 02:39:07 EDT 2012 [root@enmoteam1 oracle]# uname -r 2.6.39-200.24.1.el6uek.x86_64 [root@enmoteam1 oracle]# uname -a Linux enmoteam1 2.6.39-200.24.1.el6uek.x86_64 #1 SMP Sat Jun 23 02:39:07 EDT 2012 x86_64 x86_64 x86_64 GNU/Linux [root@enmoteam1 oracle]#
(4)/etc/redhat-release能够看到详细的版本 [oracle@enmoteam1 ~]$ cat /etc/redhat-release Red Hat Enterprise Linux Server release 6.3 (Santiago) [oracle@enmoteam1 ~]$
