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/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 \n \l
3、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
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
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
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
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"
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
