我开发了一个纯Windows批处理工具 FileNameValidator ，用于检查是否提供了批处理参数，或者是否由用户文件路径＆amp;名字是绝对的＆amp;在使用这些路径\名称运行用户代码之前，在当前Windows版本下有效。该工具不同于在SO上发布在该主题上的片段，因为它提供了用于多路径和自动化的自动用户输入验证器。文件名既可以作为批处理参数输入，也可以手动输入。其他线程解决方案基于手动单路径或使用正则表达式进行名称检查。这个工具检查路径＆amp;通过将目标文件夹测试写入磁盘来确保文件有效性。到目前为止，该工具可以检查多达9个本地或网络文件路径＆amp;名称参数。 ＆＃34;仅限本地驱动器＆＃34;限制被解除了。
我问，如何a）检查超过9个参数，b）提升代码注释中陈述的用户输入要求。在这个主题的几个SO线程中没有解决这些问题。该工具纯粹基于批处理，而其他主题则讨论C ++正则表达式或PowerShell相关技术，或FINDSTR支持的有限批处理正则表达式。
