2、uname

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

root@MyMail ~ # unameLinuxroot@MyMail ~ # uname -r2.6.18-164.el5[root@localhost ~]# uname -aLinux localhost.localdomain 2.6.18-194.el5 #1 SMP Fri Apr 2 14:58:35 EDT 2010 i686 i686 i386 GNU/Linux

3、以下二种方法适用于RedHat,CentOS

root@MyMail ~ # cat /etc/redhat-releaseCentOS release 5.4 (Final)

登录到linux执行rpm -q redhat-release

#rpm -q redhat-release或root@MyMail ~ # rpm -q centos-releasecentos-release-5-4.el5.centos.1

当前centos 版本与redhat对应的版本的命令
