查看Linux系統架構的命令,查看linux系統是哪種架構:AMD、ARM、x86、x86_64、pcc文章目錄:

1、查看內核版本
  • cat /proc/version
  • uname -a
  • uname -r

(base) shl@zhihui-mint:~$ cat /proc/version
Linux version 5.0.0-32-generic (buildd@lgw01-amd64-015) (gcc version 7.4.0 (Ubuntu 7.4.0-1ubuntu1~18.04.1)) #34~18.04.2-Ubuntu SMP Thu Oct 10 10:36:02 UTC 2019
(base) shl@zhihui-mint:~$ uname -r
5.0.0-32-generic
(base) shl@zhihui-mint:~$ uname -a
Linux zhihui-mint 5.0.0-32-generic #34~18.04.2-Ubuntu SMP Thu Oct 10 10:36:02 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux

2、查看linux版本信息
  • lsb_release -a
  • cat /etc/issue

(base) shl@zhihui-mint:~$ lsb_release -a
No LSB modules are available.
Distributor ID: LinuxMint
Description: Linux Mint 19.3 Tricia
Release: 19.3
Codename: tricia
(base) shl@zhihui-mint:~$ cat /etc/issue
Linux Mint 19.3 Tricia
l

3、查看linux是64為還是32位
  • getconf LONG_BIT
  • file /bin/ls

(base) shl@zhihui-mint:~$ getconf LONG_BIT
64
(base) shl@zhihui-mint:~$ file /bin/ls
/bin/ls: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 3.2.0, BuildID[sha1]=9567f9a28e66f4d7ec4baf31cfbf68d0410f0ae6, stripped
(base) shl@zhihui-mint:~$

4、直接查看系統的架構
  • dpkg print-architecture
  • arch
  • file /lib/systemd/systemd

(base) shl@zhihui-mint:~$ dpkg print-architecture
amd64
(base) shl@zhihui-mint:~$
(base) shl@zhihui-mint:~$ arch
x86_64
(base) shl@zhihui-mint:~$
(base) shl@zhihui-mint:~$ file /lib/systemd/systemd
/lib/systemd/systemd: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 3.2.0, BuildID[sha1]=85c772a89c42ba78383dec576b414b2b953cbe41, stripped
(base) shl@zhihui-mint:~$

關於CPU架構是x86、x86_64、amd64的叫法區別
5 查看Mint系統對應的Ubuntu系統
參考
1、使用cat /etc/os-release命令也可以獲取到 Ubuntu 代號
(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 只獲取 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基本上是同一個東西
  • x86是intel開發的一種32位指令集
  • x84_64是CPU邁向64位的時候
  • x86_64是一種64位的指令集,x86_64是x86指令的超集,在x86上可以運行的程序,在x86_64上也可以運行,x86_64是AMD發明的,也叫AMD64

現在用的intel/amd的桌面級CPU基本上都是x86_64,與之相對的arm、pcc等都不是x86_64
