如何使用脚本访问用户的 fpath 而不是系统的 fpath？

测试.zsh：

#!/usr/bin/env zsh                                                                                                           

for f in ${fpath}; do
    echo ${f}
done

输出：

/usr/local/share/zsh/site-functions
/usr/share/zsh/functions/Calendar
/usr/share/zsh/functions/Completion
/usr/share/zsh/functions/Completion/AIX
/usr/share/zsh/functions/Completion/BSD

虽然命令行输出有一些额外的条目：

如何让脚本访问用户的 fpath 而不是系统的？

答案1

您实际上无法做到这一点，因为用户fpath不是通过键值配置文件中的简单分配来设置的，而是通过潜在复杂的脚本来设置的。例如，myfpath会根据 zsh 的版本以及系统上存在的目录而有所不同。您可以获取用户的~/.zshrc，但这可能会执行各种其他操作（特别是如果 zsh 未在终端中运行，则可能无法工作，并且可能会打印内容，否则假设 shell 是交互式 shell）。

zsh source 的所有实例~/.zshenv，因此建议用户fpath从那里进行设置。
