Finding GREP calls

In my /Scripts directory I'm trying to read all scripts where I'm calling "grep".  The command I'm using is:

locate Scripts | grep \.sh | grep -rinHo "grep"

but this is giving me trash.

How do I make sure only .sh scripts are read?

OMR

Also tried:

locate /Scripts | grep \.sh | grep -rinHo "grep"
locate /Scripts | grep *.sh | grep -rinHo "grep"
locate /Scripts | grep *\.sh | grep -rinHo "grep"
