Linux命令之lsb_release - 查看當前系統的發行版信息

用途說明

lsb_release命令用來查看當前系統的發行版信息（prints certain LSB (Linux Standard Base) and Distribution information.）。有了這個命令就可以清楚的知道到底是RedHat的、還是別的發行版，還有具體的版本號，比如3.4還是5.4等等。有些系統上不一定安裝了這個命令，可以通過查看/etc/issue文件得到發行版信息。

常用參數

格式：lsb_release

格式：lsb_release -v

查看LSB本身的版本信息。

格式：lsb_release -a

打印本系統發行版的所有信息，比如發行版的ID，描述信息，具體版本，代號。

格式：lsb_release -d -s

格式：head -1 /etc/issue

查看發行版的描述信息，後面實例二展示了這個用法。
