【Linux 指令】
安裝軟體前常常需要先確認一下自己的 Linux 的版本,這裡提供兩個常用的指令 ...
- lsb_release -a : 查看 Linux 的發行版本資訊
[steven@localhost ~]$ lsb_release -a LSB Version: :core-4.1-amd64:core-4.1-noarch:cxx-4.1-amd64:cxx-4.1-noarch:desktop-4.1-amd64:desktop-4.1-noarch:languages-4.1-amd64:languages-4.1-noarch:printing-4.1-amd64:printing-4.1-noarch Distributor ID: Scientific Description: Scientific Linux release 7.3 (Nitrogen) Release: 7.3 Codename: Nitrogen
- uname -a: 查看 Linux core 的版本
[steven@localhost ~]$ uname -a
