Linux 手册页字母索引

这个页面基于 man7.org 的字母索引页做了站内整理。命令名和原始链接保持准确，说明、导航和分区提示改成中文，同时为了云端访问速度，默认只渲染当前字母分组。

手册分区说明

1用户命令与常用可执行程序
2系统调用接口
3C 函数库与开发接口
5文件格式、配置文件与约定
7概览、约定、协议与杂项
8系统管理命令

像 accept(2) 这样的写法，括号里的数字就是它所属的 man 分区。先看名字，再看分区，判断会更快。

使用方式

1. 先选字母

这页已经改成按字母查看，首屏不会再一次性加载全部条目，更适合云端访问。

2. 再看分区

同名条目可能出现在不同分区，例如普通命令、系统调用、POSIX 版本或库函数版本。

3. 需要原文就点进 man7

每个条目都保留了原始 man7 链接，适合继续阅读完整英文手册页。

4. 搜索只过滤当前分组

为了避免把整份索引都塞进页面里，当前搜索只在你打开的字母分组内即时过滤。

字母导航

点击字母切换分组。现在默认只渲染当前分组，访问速度会比整页全部展开稳定很多。
