关于cpu架构是x86、x86_64、amd64的叫法区别

参考

1、使用cat /etc/os-release命令也可以获取到 ubuntu 代号

(base) shl@zhihui-mint:~$ cat /etc/os-release
name="linux mint"
version="19.3 (tricia)"
id=linuxmint
id_like=ubuntu
pretty_name="linux mint 19.3"
version_id="19.3"
home_url="https://www.linuxmint.com/"
support_url="https://forums.linuxmint.com/"
bug_report_url="http://linuxmint-troubleshooting-guide.readthedocs.io/en/latest/"
privacy_policy_url="https://www.linuxmint.com/"
version_codename=tricia
ubuntu_codename=bionic
(base) shl@zhihui-mint:~$ 

2、使用 cat /etc/upstream-release/lsb-release 只获取 ubuntu 的基本信息

(base) shl@zhihui-mint:~$ cat  /etc/upstream-release/lsb-release
distrib_id=ubuntu
distrib_release=18.04
distrib_codename=bionic
distrib_description="ubuntu 18.04 lts"
(base) shl@zhihui-mint:~$ 

注意：

x86_64，x64，amd64基本上是同一个东西

• x86是intel开发的一种32位指令集
• x84_64是cpu迈向64位的时候
• x86_64是一种64位的指令集，x86_64是x86指令的超集，在x86上可以运行的程序，在x86_64上也可以运行，x86_64是amd发明的，也叫amd64

现在用的intel/amd的桌面级cpu基本上都是x86_64，与之相对的arm、pcc等都不是x86_64
