Linux命令之lsb_release：查看当前系统的发行版信息

Linux里的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。
