Windows CMD: List files in dir & subdir WITHOUT given extensions
提问by DapperDan
I'd like to recursively search a directory and find files, which have NOT a certain extension, or precisely, which have NOT a certain set of extensions.
我想递归搜索目录并找到没有特定扩展名的文件，或者准确地说，没有特定的扩展名集。
Sketch: find in "dir" all files without "ext1", "ext2", "ext3" and print results to .txt
草图：在“目录”中查找所有没有“ext1”、“ext2”、“ext3”的文件并将结果打印到 .txt
I tried around several hours with DIR and ATTRIB, but unfortunately without bigger success.
我用 DIR 和 ATTRIB 尝试了几个小时，但不幸的是没有取得更大的成功。
Your consideration is highly regarded! Thanks.
您的考虑受到高度重视！谢谢。

Try this:
尝试这个：
dir /b /s /a-d | findstr /vi ".ext1$ .ext2$ .ext3$"
The /a-dswitch excludes directories, giving you only files. The findstrparameter lets you search the files for strings, and the /viswitch indicates to exclude files containing the next parameter, the search being case insensitive.
该/a-d开关不包括目录，让你只文件。该findstr参数允许您在文件中搜索字符串，/vi开关指示排除包含下一个参数的文件，搜索不区分大小写。
As Joey pointed out, the $is necessary to indicate end of the line.
正如乔伊指出的那样，$必须指示行的结尾。
