Recursively find files with a specific extension

Question

I'm trying to find files with specific extensions. For example, I want to find all .pdf and .jpg files that's named Robert

I know I can do this command

$ find . -name '*.h' -o -name '*.cpp' 

but I need to specify the name of the file itself besides the extensions. I just want to see if there's a possible way to avoid writing the file name again and over again Thank you !

Answer 1

My preference:

find . -name '*.jpg' -o -name '*.png' -print | grep Robert
