效果预览

执行脚本效果预览

补充说明

该脚本用于在 Proxmox VE (PVE) 环境中交互式卸载已安装的内核及头文件包，自动保护当前运行的内核和基础包，支持选择性卸载和一键清理非当前内核版本，操作完成后自动更新 GRUB 配置。

功能特点

智能保护：自动识别并保护当前运行的内核，禁止卸载
基础包保护：proxmox-kernel-7.0 等基础包标注为不建议卸载
一键清理：输入 X 一键卸载所有非当前运行的内核及头文件
单包卸载：输入序号选择性卸载指定内核或头文件包
确认机制：卸载前二次确认，防止误操作
自动更新 GRUB：卸载完成后自动执行 update-grub 更新引导配置
日志记录：卸载操作自动记录到 /var/log/pve-kernel-cleanup.log
彩色交互：全程彩色输出，当前运行内核高亮标注

交互说明

操作	说明
`0`	退出脚本
`X` / `x`	一键卸载其他（非当前运行）内核及头文件
`1` / `2` / `3` ...	输入序号，卸载指定的单个内核或头文件包

安全保护规则

规则	说明
当前运行内核	不可卸载，列表中以黄色标注 `## 当前运行, 不可卸载`
`proxmox-kernel-7.0`	基础包，不建议卸载，列表中以黄色标注 `## 基础包, 不建议卸载`
其他内核/头文件	可卸载，卸载前需输入 `y` 二次确认

注意事项

必须使用 root 权限运行（脚本会自动检测）
需要在 Proxmox VE 节点上运行
卸载后自动更新 GRUB，建议卸载完成后重启节点
谨慎卸载内核，确保至少保留一个可用内核版本
日志文件路径：/var/log/pve-kernel-cleanup.log
