在Linux环境下，可以通过以下命令快速获取系统和硬件信息。最后将这些命令整合成一个脚本（如 `sysinfo.sh``），一键输出所有信息。
1. 系统信息
# 内核信息
uname -a# 发行版信息
lsb_release -a 2>/dev/null || cat /etc/*release*# 系统启动时间
uptime# 环境变量
echo "PATH: $PATH"
2. 硬件信息
# CPU信息
lscpu
cat /proc/cpuinfo | grep "model name" | uniq# 内存信息
free -h
cat /proc/meminfo | grep "MemTotal"# 磁盘和分区
lsblk
df -h# PCI设备（GPU、网卡等）
lspci# USB设备
lsusb# 主板和BIOS（需要root）
sudo dmidecode -t baseboard
sudo dmidecode -t bios# 电池信息（笔记本）
upower -i /org/freedesktop/UPower/devices/battery_BAT0
3. 显卡信息
# NVIDIA显卡（需安装驱动）
nvidia-smi 2>/dev/null# 通用GPU信息
lspci | grep -i vga
4. 网络信息
# IP和接口
ip addr
hostname -I# 路由表
ip route# DNS配置
cat /etc/resolv.conf# 网络管理器状态（需安装NetworkManager）
nmcli dev status
5. 已安装软件
# Debian/Ubuntu
dpkg -l# RedHat/CentOS
rpm -qa# Snap包
snap list# Flatpak包
flatpak list
6. 整合脚本
将以下内容保存为 sysinfo.sh，运行 bash sysinfo.sh 输出到文件：
#!/bin/bash{echo "===== 系统信息 ====="uname -alsb_release -a 2>/dev/null || cat /etc/*release*uptimeecho -e "\n===== CPU信息 ====="lscpuecho -e "\n===== 内存信息 ====="free -hecho -e "\n===== 磁盘信息 ====="lsblkdf -hecho -e "\n===== 显卡信息 ====="lspci | grep -i vganvidia-smi 2>/dev/nullecho -e "\n===== 网络信息 ====="ip addrhostname -Iecho -e "\n===== 环境变量 ====="echo "PATH: $PATH"} | tee system-info.txtecho "信息已保存到 system-info.txt"
7. 其他工具推荐
inxi：综合信息工具（需安装sudo apt install inxi）inxi -Fxzneofetch：美观的系统信息工具（需安装）neofetch
通过上述命令，可以快速全面地获取Linux系统的软硬件配置信息。
8.输出结果
最后输出的结果展示如下：
脚本:
> touch sysinfo.sh
> vim sysinfo.sh
> ll sysinfo.sh
-rw-rw-r-- 1 tipriest tipriest 552 3月 17 14:58 sysinfo.sh
> sudo chmod +x ./sysinfo.sh
