The problem with your command is not portability (it's specific to bash, of course, but there's no problem on the grep side). The problem is that you're grabbing some lines in function definitions. Bash indents most of the function code, but not all of it, in particular not text inside here documents (f () {|cat <<EOF|foo=bar|EOF|} where | represents a line break).
