That doesn't seem to do anything . .
then you probably don't have any files named 'a.rb' under the current

Not quite. For better (maximum?) robustness, pass '-print0' to find and
'-0' to xargs. That will handle filenames with spaces and/or quotes
correctly. (If your filenames have bytes with binary value zero in them,
you still will be out of luck)

Know an OS where that is allowed?
NT 4 kernel mode API is quite happy with \0 in filenames. But it
*really* confuses the Win32 layer! Haven't played with later
versions...
So you need to pass the filename size all over? Ugh.
I was just obliquely pointing out the lack of ^ and \. and $ But
it's true that Dir. is not very seletcive.... In fact, I think I
once submitted an RCR to let it take a second argument that would be
tested for (like: Dir["**/**"],?f]) but it was rejected. So here I am
several years later still acting as if Dir. could read my mind....
