shell實現(xiàn)多級菜單腳本編寫的示例代碼

更新時間：2024年02月27日 08:28:52 作者：[禾火]

本文主要介紹了shell實現(xiàn)多級菜單腳本編寫，文中通過示例代碼介紹的非常詳細，對大家的學習或者工作具有一定的參考學習價值，需要的朋友們下面隨著小編來一起學習學習吧

1. 提示

本腳本主要實現(xiàn)多級菜單效果，并沒有安裝LAMP、LNMP環(huán)境，如果要用在實際生成環(huán)境中部署LNMP、LAMP環(huán)境，只需要簡單修改一下就可以了。

2. 演示效果

2.1. 一級菜單

2.2. 二級菜單

2.3. 執(zhí)行操作

3. 參考代碼

#!/bin/bash
#
