-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 invocations 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.
