Ah, thanks for clearing few things! :-) Is this why xargs is more efficient?

This thing pointed out the difference:
$ ls | xargs echo
vs.
$ ls | perl -lane 'print $F[0]'

:-)

For others who might be reading this, find also has a similar option.
From it's manpage:

    -exec utility [argument ...] {} +
       Same as -exec, except that ``{}'' is replaced with as many pathnames as
       possible for each invocation of utility. This behaviour is similar to
       that of xargs(1).
