linux查看系统相关信息
一、查看Linux内核版本信息：
常用的三个命令
$cat /proc/version
1 | Linux version 4.15.0-144-generic (buildd@lgw01-amd64-031) (gcc version 7.5.0 (Ubuntu 7.5.0-3ubuntu1~18.04)) #148-Ubuntu SMP Sat May 8 |
02:33:43 UTC 2021
$uname -a
1 | Linux aiserver 4.15.0-144-generic #148-Ubuntu SMP Sat May 8 02:33:43 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux |
$lsb_release -a
1 2 3 4 5 | No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 18.04.5 LTS Release: 18.04 Codename: bionic |
二、查看硬件信息：
CPU
lscpu

df 命令显示文件系统的磁盘空间使用情况
df -h

三、系统资源监控
top 和 htop，可以显示 CPU 的使用率、进程列表等信息，htop需要安装
sudo apt-get install htop
