system_tools.sh_v1.9

【v1.9】 Ninth Version, This version fixes the issue where the script did not check if ipset was already installed before creating Docker firewall configuration files. It optimizes and changes the terminal interaction logic when managing SSH firewall rules and Docker firewall rules.When a user chooses not to create a configuration file, the script will first check if the configuration file already exists in the system. This approach introduces a validation logic to prevent mistakenly proceeding directly to the file creation step, which may not be the best user experience. Similarly, when the user chooses to modify an existing configuration file, the script will also first check if the corresponding configuration file already exists in the system, applying the same validation logic.In previous versions, the script only checked if the configuration file existed right before actually creating it. Now, this check has been moved up to the interaction inquiry phase. This change ensures that before any configuration file is created, the system confirms the absence of the corresponding configuration file, avoiding any blind file creation. All actions are carried out under a transparent logical environment for the script's sensitive operations. The previous detection step is now converted into corresponding prompt messages.(2024.08.25 Night)

【v1.9】 第九版，修正创建 Docker 防火墙配置文件时，未判断 ipset 是否已经安装的问题，优化以及变更管理 SSH 防火墙规则以及管理 Docker 防火墙和规则时终端交互的逻辑层次，当选择未创建配置时会首先判断系统中是否已经存在配置文件，这是一种质疑逻辑，避免选择失误进而造成直接进入创建配置文件的环节，显然直接进入下一环节并不是最佳的终端交互体验方式，另外，当选择修改相应的配置文件时，也会首先判断系统中是否已经存在对应的配置文件，同样也是质疑性质的逻辑，之前的版本中，在最终创建配置文件的之前才会检测系统是否已经存在配置文件，现在这种检测被提前到交互询问的环节，这一切都时为了在创建任何配置文件之前，都能确保系统中确实没有相应的配置文件，而不是直接盲目的创建任何文件，一切都需要在透明的逻辑环境下进行脚本的敏感操作，至于之前的检测环节，变更为相应的提示语。（2024.08.25夜）
