I have done as you suggested (did you?). And my observation is that ls ./*/* reports first on files that are one level below the current directory, i.e. files in the immediate sub-directories (which is what I want). And in addition ls seems to automatically recurse if given a wildcard. So it also reports recursively on sub-directories of those one-level-down directories. My explanation: 
   .      the current directory
    /*    all dirs in next level down
      /*  all files in those dirs

[download]
and recurse from there.

If the recursion happens with the perl example, it doesn't matter in my case since there is nothing there.

I'd still like to know if %perl -pie 's/old/new/g' ./*/* does what I want.

Meditation: This whole thing has taken a direction that I am bemused by. I thought I was asking a simple and straightforward question. The discussion has ranged far and wide. And I find myself in the position of 'arguing' with answers that seem not to answer the question I asked but rather go in different directions. If I am seeming ungrateful, ungracious, or argumentative, I apologize. I really am just trying to get clarity on my measily half-line solution.

If my solution does not do what I want, just say that and explain where I have gone astray. And if my solution fails, I would be very happy to see a pure-perl command-line solution if that is possible.

Thanks to all for your (presumed) patience.
