Shell编程(创建菜单并将其定向到菜单本身) [英] Shell Programming (Creating Menu and directing it to menu itself)

问题描述

我应该在shell编程中创建一个菜单，其中包含一个类似这样的主菜单.

1)添加新书
2)删除现有的图书信息
3)更新图书信息和数量
4)按书名/作者搜索书
5)处理售出的书
6)库存汇总报告
7)退出


每个选择都应该将我带到该页面的下一页.
有人有示例源代码吗?我尝试使用Google搜索，但也找不到所需的教程.也许我缺乏对Shell编程的了解，我也需要知道是否能够选择一个菜单，该菜单会将其定向到该特定菜单，也许存储在另一个.sh文件中?

非常感谢:)

I''m supposed to create a menu in shell programming comprises of a main menu something like this..

1) Add new book
2) Remove existing book info
3) Update book info and quantity
4) Search for book by title/author
5) Process a book sold
6) Inventory summary report
7) Quit


Each selection supposed to bring me to next page of it.
Anyone had the sample source code of it? I tried googling it around, can''t find the desired tutorial for it too. Perhaps my lack of understanding on shell programming, I need to know too on be able to select a menu, which would direct it to that particular menu, perhaps stored at another .sh file?

Thanks a lot :)

推荐答案

由于您提到了.sh文件，所以我想您的意思是Unix或Linux shell脚本.尽管您可以使用几种不同类型的Shell语言-sh/bash，tcsh/csh，ksh ...

对于它们中的任何一个，查找信息的最佳位置是手册页-在命令行中使用"man bash"或"man csh".

Since you mention a .sh file, I guess you mean Unix or Linux shell scripting. There are several different types of shell language that you could be using though - sh/bash, tcsh/csh, ksh ...

For any of them the best place to look for information is the manual page - use "man bash" or "man csh" from the command line.

使用以下代码:menu.sh

Use the below code: menu.sh
