1、检察内核版本
- 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
复制代码 2、检察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
复制代码 3、检察linux是64为照旧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:~$
复制代码 4、直接检察系统的架构
- 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:~$
复制代码 关于CPU架构是x86、x86_64、amd64的叫法区别
5 检察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:~$
复制代码 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:~$
复制代码 留意:
x86_64,x64,AMD64基本上是同一个东西
- x86是intel开辟的一种32位指令集
- x84_64是CPU迈向64位的时间
- x86_64是一种64位的指令集,x86_64是x86指令的超集,在x86上可以运行的步伐,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
