每次我需要获取一些 Zsh 信息时，我终于厌倦了通过手册页和在线搜索进行搜索。我浏览了 Zsh 的所有手册页，并整理了一个很好的“帮助”功能，该功能相当广泛。
要使用它，我会在您的某处创建一个名为“帮助”的文件fpath并添加autoload -Uz help到您的 zshrc.xml 文件中。

它使用 less 作为分页器，并为彩色手册页启用了 less 的 termcap 支持。help不带参数执行--help或-h列出保留字和内置命令。使用其中一个词键入help会直接进入相应手册页中的条目。我浏览并缩小了特定手册页中的条目以优化速度/效率，而不仅仅是使用man ... zshall. 这个帮助功能发现的不仅仅是保留字和内置命令。它将定位模块、模块命令、某些重要的完成命令（如 compadd、compset 等）的条目。
许多关于算术、完成、通配、数组、环境变量、异常处理等内容的部分通过键入help math, help complet, help glob, help arrays, help env,来显示help except。有通配符和多个匹配项使帮助功能更加友好。这是一个相当简单的 case 语句，有超过 210 个匹配条件。如果没有匹配项，则默认为 zshall 搜索。如果匹配条件未显示您要查找的内容或似乎妨碍help --您，请在搜索词后面键入以绕过所有匹配。
我包含了很多 Zsh 手册页所涵盖的内容，但可以通过包含下划线前缀完成函数之类的内容来使其更智能或更完整。
^[h编辑：我为(esc/alt + h)做了一个 bindkey 函数。run-help默认情况下绑定在那里，这将替换它。
_helpprefix(){
OLDBUFFER="$BUFFER"
zle backward-kill-word
BUFFER="help $CUTBUFFER"
zle accept-line
zle -U "$OLDBUFFER"
}
zle -N _helpprefix _helpprefix
bindkey '^[h' _helpprefix
它的作用是删除最后输入的单词，help使用该单词执行，然后将其推回原始行。read因此，您可以使用它在如下命令中运行帮助：
find /usr -print0 | while IFS= read
在查看read.
另外值得注意的是，如果您需要有关特定内置标志的帮助，您可以随时-在命令后添加 a 并点击 tab 以查看每个标志的简短描述，例如read -+ tab 将其打印出来：
-A -- first name is taken as an array
-E -- input read is echoed
-d -- specify delimiter to terminate input instead of newline
-e -- input read is echoed and not assigned
-k -- specify number of characters to read
-q -- read y or n character from terminal
-r -- raw mode
-s -- suppress terminal echoing
-t -- test if input is available before reading
-u -- specify file descriptor to read from
-z -- read entry from editor buffer stack
