Linux命令lsb_release：查看當前系統的發行版信息

Linux裡的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。
