How to restrict file extension when using grep with a directory parameter?

Question

grep -nr 'queryTag' .

For example, I have a number of directories in the current directory, and I want to search for the keyword 'queryTag'. However, I want to restrict the search to the file type '.txt', not all the file in the current directory. How to modify the command above?

You can use --include= option:

grep -nr 'queryTag' --include='*.txt' .
