macos - macOS 中名为 "prompt"的 zshell 命令？

Question

我正在为 macOS Catalina (10.15.6) 使用 zshell。 《Learning Shell Scripting With Zsh》一书描述了一个名为 prompt 的可执行命令。 ，可用于以下形式:

$ prompt -p
$ prompt -h
$ prompt <theme_name>
$ prompt adam1 red yellow magenta

但是 zsh 报告“找不到命令:提示”。
我如何获得该命令或等效的命令。
(我尝试搜索的所有地方都提供了指向解释如何设置 zsh 提示的地方的链接，以及所有常用的转义序列、“$...”符号等)

来自 man zshcontrib :

PROMPT THEMES
   Installation
       You  should  make  sure  all  the  functions from the Functions/Prompts
       directory of the source distribution are available; they all begin with
       the  string `prompt_' except for the special function`promptinit'.  You
       also  need  the  `colors'  and  `add-zsh-hook'  functions  from   Func-
       tions/Misc.   All these functions may already be installed on your sys-
       tem; if not, you will need to find them and copy them.   The  directory
       should  appear  as  one of the elements of the fpath array (this should
       already be the case if they were installed), and at least the  function
       promptinit  should  be autoloaded; it will autoload the rest.  Finally,
       to initialize the use of the system you need  to  call  the  promptinit
       function.   The  following  code  in your .zshrc will arrange for this;
       assume the functions are stored in the directory ~/myfns:

              fpath=(~/myfns $fpath)
              autoload -U promptinit
              promptinit

所以，要得到 prompt命令，你可以运行

$ autoload -U promptinit
$ promptinit
