I usually use grep when I require to find things. I personally do not
understand why the unix units contain function names with the prefix
of Fp, but it does not matter, because the name remains, so I do
something like

grep -in functionname ./location/* -R | grep -v "something I do not
wish to be included"

And I find what/where what I wish to have is located... It's good btw
for anything you do not remember/know where/how it is located ...
