是否有等效于内置 bash `help` 的 zsh？

  • 772

在 bash 中，我可以使用该help命令打印特定内置命令的概要

$ help pwd
pwd: pwd [-LP]
    Print the name of the current working directory.

    Options:
      -L    print the value of $PWD if it names the current working
            directory
      -P    print the physical directory, without any symbolic links

    By default, `pwd' behaves as if `-L' were specified.

    Exit Status:
    Returns 0 unless an invalid option is given or the current directory
    cannot be read.

zsh中是否有等价物，还是我只使用man zshbuiltins？

    如@DavidPostill 评论中的 Stack Overflow 问题所示，将其放入：~/.zshrc

    unalias run-help
autoload run-help
HELPDIR=/usr/share/zsh/"${ZSH_VERSION}"/help
alias help=run-help

    如果您在 macOS 上并使用 Homebrew 安装，那么您将需要用以下代码替换该HELPDIR行：

    HELPDIR=$(command brew --prefix)/share/zsh/help
