shell脚本用户管理程序

Question

我正在编写一个 bash 脚本来添加编辑和删除用户。我无法让它工作。谁能看到我哪里出错了？我已通过创建用 .sh 保存的空文档将 .sh 文件添加到指定文件夹中。当我输入选项 1 或 2 时，它只是要求我再次输入一个选项，而选项 3 显示为 ERROR。 这是我的升级代码 问题是我仍然无法创建文件

主菜单代码

#!/bin/bash
trap ''2
title="////////////////////
10101010101010101010
///main user menu///
10101010101010101010
////////////////////
"
clear
echo "$title"

PS3='Select option: '
choice=("Create User" "Edit User" "Remove User" "Exit")
select cho in "${choice[@]}"
do
    case $cho in
        "Create User")
            /home/hiphappy1/Documents/Courseworkfiles/Users.sh
            ;;
        "Edit User")
            /home/hiphappy1/Documents/Courseworkfiles/EditUser.sh
            ;;
        "Remove User")

Answer 1

必须在答案中写下这一点，因为它需要更详细的示例，并且是调用其他可执行文件的一般设计考虑因素。

在您的子菜单中，您询问是否要返回主菜单。您不应该回电Menu.sh，因为您正在添加另一个层或子流程。相反，您应该允许例如CreateMenu.sh 正常退出，这将流回Menu.sh，此时您从select 循环中break 并使用while 循环返回顶部以再次显示菜单。代码如下：

菜单.sh

#!/bin/bash
trap ''2
title="////////////////////
10101010101010101010
///main user menu///
10101010101010101010
////////////////////
"
clear
echo "$title"
courseworkfiles="/home/hiphappy1/Documents/CourseworkFiles"
PS3='Select option: '
choice=("Create User" "Edit User" "Remove User" "Exit")
finished=0
while (( !finished )); do
    select cho in "${choice[@]}"
    do
        case $cho in
            "Create User")
                "$courseworkfiles/CreateUser.sh"
                break
                ;;
            "Edit User")
                "$courseworkfiles/EditUser.sh"
                break
                ;;
            "Delete User")
                "$courseworkfiles/RemoveUser.sh"
                break
                ;;
            "Exit")
                finished=1
                break
                ;;
            *)
                echo "ERROR try again"
                ;;
        esac
    done
done

创建用户.sh

#!/bin/bash
# ...code to create user...
# 
# ..echo some sort of confirmation message
#
# then do nothing, no read, no case, just let if flow back to Menu.sh
