1、查看内核版本
- 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/Linux2、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 n l3、查看linux是64为还是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:~$4、直接查看系统的架构
- dpkg --print-architecture
- arch
- file /lib/systemd/systemd
(base) shl@zhihui-mint:~$ 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:~$
关于CPU架构是x86、x86_64、amd64的叫法区别
5 查看Mint系统对应的Ubuntu系统参考
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
