I admit that it is a rather nice paradign.  And again I never use
whitespace in filenames so it always works perfectly for me.

But now I have to point out the GNU find -regex option. :-)

  find some/path -regexp 'some.*regex' -exec grep 'some-string' {} +

The only gotcha is that the regular expression must match the entire
pathname.  It is anchored on both ends.  So use of .* is usually normal.

But of course -regex is an extension and so isn't portable everywhere.
