Batch file 创建批处理文件以提示响应并替换文本或.ini文件中的文本行

我已经让批处理文件为第一行工作，但是当我尝试添加一个额外的for循环以获取下一行文本时，它实际上复制或复制了文本，而不是替换它。 当前批处理文件甚至不会更改.txt文件。 代码如下--

如果目标是根据原始文件的内容创建更新的文件，则需要测试文件内容的值，对其进行相应修改，将修改后的行输出到新文件，然后使用“重命名”将原始文件替换为新版本。在您当前的脚本中，您似乎只是将修改过的行添加到文件中。我只是让它将这些行作为“查找并替换”来读取，它对一行有效，因此是一个“for”循环，但是如果我添加另一个循环来更改另一行，它将不起作用。您无法从文件中读取，也无法从类似的文件写入同一文件。我也看不出为什么不能在原始循环中执行第二个替换，而不是添加另一个替换，从而在不必要时加倍工作。此代码实际上已经在读写同一个.txt文件。我将尝试在第一个循环中添加第二个循环，看看t是否有效。谢谢@compotechnology，您的第一个循环既从同一个文件读取，又附加到同一个文件。不要这样做！任何事情出了问题，你都可能失去这两个。首先创建备份，然后读取备份，同时写入原始文件。一旦验证了原始文件的正确性，就可以选择删除备份。
