更新時(shí)間：2024年02月27日 08:28:52 作者：[禾火]

本文主要介紹了shell實(shí)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(xì)，對大家的學(xué)習(xí)或者工作具有一定的參考學(xué)習(xí)價(jià)值，需要的朋友們下面隨著小編來一起學(xué)習(xí)學(xué)習(xí)吧

1. 提示

本腳本主要實(shí)現(xiàn)多級菜單效果，并沒有安裝LAMP、LNMP環(huán)境，如果要用在實(shí)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
