Mac里使用man-db实现中文man

前置条件：需要brew

网上很多使用 https://github.com/man-pages-zh/manpages-zh来配置mac里中文man手册的，但是这种方法配置出来的man的用法与实际用法可能并不一致，且该过程复杂，需要本地clone再cmake，极其麻烦

本文给出一种使用第三方库man-db来替换原本man来配置man中文手册的方法

Step1:按照man-db

brew install man-db

安装log

brew install man-db

==> Caveats
Commands also provided by macOS have been installed with the prefix "g".
If you need to use these commands with their normal names, you
can add a "bin" directory to your PATH from your bashrc like:
  PATH="/opt/homebrew/opt/man-db/libexec/bin:$PATH"

==> Running `brew cleanup man-db`...
Disable this behaviour by setting HOMEBREW_NO_INSTALL_CLEANUP.
Hide these hints with HOMEBREW_NO_ENV_HINTS (see `man brew`).

Step2:设置系统变量Lang

PATH="/opt/homebrew/opt/man-db/libexec/bin:$PATH"
export LANG=zh_CN.UTF-8

配置该系统变量即可，这里笔者用的是zsh

open ~/.zshrc

新增并保存即可

最后重载终端

可以看到已经生效
