Windows command line search for exact extension with dir

问题

When I do a search:

dir /b /s *.txt

I get all files/folders with the extension .txt. But I also get them when they have an extension like .txtx. How can I search for the exact extension?

回答1:

you can try this

dir  /s /b *.txt | findstr /v .txt.

or

dir  /s /b *.txt | findstr /e .txt

or

dir  /b *.txt | findstr  .txt$

I can't figure out why it behaves like this, but this works: dir /b /s .txt | findstr /e .txt. Ugly but works.
