Question

我有bash脚本来安装tomcat和java，这将基于用户选择输入而发生，如我们所料，它运行良好。当java和tomcat不存在时，它将按照以下代码一一配置。如果tomcat和Java已经存在，它将通过终端中的错误进行处理。

#!/bin/bash

tomcat_base_dir=/sys/workers
java_base_dir=/usr/lib/java
software_location=/home/softwares/

PS3='Please enter your choice: '

echo "==========================="
echo "Softeare Setup"
echo "==========================="

options=("Option 1: Tomcat Installation" "Option 2: Java Installation" "Option 3: Reply" "Quit")

COLUMNS=12
select opt in "${options[@]}"; do
        case $opt in

        "Option 1: Tomcat Installation")
                echo "you chose choice 1"

                echo "Tomcat Installation"
                echo "================================================================"
                if [ ! -d $tomcat_base_dir ]; then
                        echo "Error directory $tomcat_base_dir does not exists!"
                        mkdir -p /sys/workers
                        cp -r $software_location/apache*.gz $tomcat_base_dir
                        echo "tomcat file copied"
                        cd $tomcat_base_dir && tar zxf apache*.gz -C . && rm -rf apache*.gz && mv a* tomcat
                        echo "Tomcat tar file removed and renamed as well"
                        echo "Tomcat Version"
                        tomcat_output="$(cd $tomcat_base_dir/bin && ./version.sh | grep -i "Server version")"
                        echo "============================"
                        echo "${tomcat_output}"
                        echo "============================"
                else
                        echo "$tomcat_base_dir directory found!"
                fi
                ;;

        "Option 2: Java Installation")

                echo "you chocie 2"
                echo "Java Installation"
                echo "================================================================"

                if [ ! -d $java_base_dir ]; then
                        echo "Error directory $java_base_dir does not exists!"
                        mkdir -p /usr/lib/java
                        cp -r $software_location/jre*.gz $java_base_dir
                        echo "java file copied"
                        cd $java_base_dir && tar zxf jre*.gz -C . && rm -rf jre*.gz && mv j* jre
                        sudo update-alternatives --install "/usr/bin/java" "java" "/usr/lib/java/jre/bin/java" 1
                        sudo update-alternatives --install "/usr/bin/javaws" "javaws" "/usr/lib/java/jre/bin/javaws" 1
                        echo "Java Runtime Environment installtion completed"
                        java_output="$(java -version 2>&1 | head -n 1 | cut -d\" -f 2)"
                        echo "============================"
                        echo "${java_output}"
                        echo "============================"
                else
                        echo "$java_base_dir directory found!"
                fi
                ;;

        "Option 3: Reply")

                echo "Reply"
                echo "================================================================"
                echo "you chose choice $REPLY which is $opt"
                ;;

        "Quit")
                break
                ;;

        *) echo "invalid option $REPLY" ;;
        esac
done

现在的问题是，当我选择选项1时，我必须选择我在机箱内拥有的所有选项，例如（选项1 java安装和选项2 tomcat安装）。当我使用选项2 tomcat时会安装。

现在我要使用all选项安装两个软件。

为每个单独的安装创建功能或脚本，并添加用于安装这两种功能的脚本：

select opt in "${options[@]}"; do
    case $opt in

    "Option 1: Tomcat Installation")
        install_tomcat
        ;;
    "Option 2: Java Installation")
        install_java
        ;;
    "Option GREEDY: Install everything")
        install_tomcat; install_java
        ;;
    ....

Bash脚本安装软件
