# nb: 命令行笔记/书签/知识库工具 速查
# 来源: https://github.com/xwmx/nb 官方文档 (xwmx.github.io/nb)
# 本质: 单 bash 脚本, 纯文本(默认 markdown), 内置 Git 版本记录与同步
# 笔记默认全局存于 ~/.nb, 首次运行 nb 自动建 home 笔记库
nb add / nb a # 无参数 → 打开编辑器新建空白笔记
nb add -t "标题" # 指定标题 → 自动打开编辑器(实测确认, 最常用)
nb add -t "标题" "正文内容" --tags a,b,c # 标题 + 正文一并给定, 不开编辑器
nb ls # 列出所有笔记(带编号)
nb ls "关键词" # 按文件名/标题过滤
nb show 2 # 查看编号 2
nb show 2 --print # 直接打印到终端(不再分页)
nb delete 2 # 删除编号 2
nb edit 2 # 编辑编号 2 (最常用: 先 nb ls 看编号)
nb search / nb q # 全文搜索
nb search --tag docker # 按标签搜索
