+
+安装缺失的基础工具（fish、tmux、git），随后依次执行：
+  1. fish-init  初始化 Fish 配置、插件与默认 shell
+  2. tmux-init  初始化 tmux 配置与 TPM 插件
+  3. git-init   初始化 Git 配置
+
+支持:
+  macOS        Homebrew
+  Debian/Ubuntu apt
+
+选项:
+  -h, --help  显示此帮助
+
+说明:
+  请以需要配置的普通用户运行，不要使用 sudo 运行本脚本。
+  Linux 安装缺失软件时会请求 sudo；Fish 初始化也会请求 sudo 将 fish
+  加入 /etc/shells。
