Wrong.

       -exec command {} +
              This variant of the -exec option runs the specified command on
              the selected files, but the command line is built by appending
              each selected file name at the end; the total number of  invo-
              cations  of  the  command will be much less than the number of
              matched files.  The command line is built in much the same way
              that  xargs  builds  its  command lines.  Only one instance of
              ’{}’ is allowed within the command.  The command  is  executed
              in the starting directory.

And yes, that works on mostly any Unix (as said: SUSV compliant), while
many commercial unixes have "interesting" implementations of xargs and
-print0 (or don't have that at all).

Cheers,

Ralph
