Question

Is there a simple bash executable program (SIMPLE!!! in the repositories!) to iterate the file tree in a specified order (infix, prefix, postfix whatever) while executing a function on the files?

Specifically i want to make a large list of the names of files on the root of one or more dirs. I could do this on java easy (in fact i already have the function) but i want to do it in bash for some reason).
I’m not interested in code. I want to use a program that takes care of that for me.

You could use

find . -type f -exec cat {} \;

…to find all files -type f in the current directory ., and show the contents of each one cat {} \;.
Or you could use tree if you want a tree-like output (this one is not installed by default though).
