Filenames with blanks

Thank you for interesting remark, Wayne.

I made a test directory with only one file there ("Conference Calls"), so
that if I run find for files only and quote output, that should be the
equivalent of the COM you suggested. Still, it gets split on white space.
You are definetely right about ticks, because if I replace COM for
explicit quoted filename, that works fine.

Still, I am not sure if I understand your suggestion. Looks like you are
saying: have output from COM like this:
/a/b/c d

May be each line quoted. And this is exactly what I already have when I
run this command on the SRC host. Still it is being splitted on white.
Please clarify if your COM would produce this output or not.
