查看当前系统的发行版信息

lsb_release命令用来查看当前系统的发行版信息(prints certain LSB (Linux Standard Base) and Distribution information.)。有了这个命令就可以清楚的知道到底是RedHat的、还是别的发行版,还有具体的版本号,比如3.4还是5.4等等。有些系统上不一定安装了这个命令,可以通过查看/etc/issue文件得到发行版信息。 

常用参数

格式:lsb_release

格式:lsb_release -v

查看LSB本身的版本信息。 

格式:lsb_release -a

打印本系统发行版的所有信息,比如发行版的ID,描述信息,具体版本,代号。 

格式:lsb_release -d -s

格式:head -1 /etc/issue

查看发行版的描述信息,后面实例二展示了这个用法。
