Really?
Code:
[aia@arrow many]$ ls -l
total 0
[aia@arrow many]$ 
[aia@arrow many]$ find . -name "do_not_exit" -print0 | xargs rm
rm: missing operand
Try 'rm --help' for more information.
[aia@arrow many]$ find . -name "do_not_exit" -print0 | xargs

[aia@arrow many]$ find . -name "do_not_exit" -print0
[aia@arrow many]$

Ace::Graphics::Glyph::arrow(3pm)			User Contributed Perl Documentation			  Ace::Graphics::Glyph::arrow(3pm)

NAME

       Ace::Graphics::Glyph::arrow - The "arrow" glyph

SYNOPSIS

	 See L<Ace::Graphics::Panel> and L<Ace::Graphics::Glyph>.

DESCRIPTION

       This glyph draws arrows.  Depending on options, the arrows can be labeled, be oriented vertically or horizontally, or can contain major and
       minor ticks suitable for use as a scale.

   OPTIONS
       In addition to the common options, the following glyph-specific options are recognized:

	 Option      Description	       Default
	 ------      -----------	       -------

	 -tick	     Whether to draw major	 0
		     and minor ticks.
		     0 = no ticks
		     1 = major ticks
		     2 = minor ticks

	 -parallel   Whether to draw the arrow	 true
		     parallel to the sequence
		     or perpendicular to it.

	 -northeast  Whether to draw the	 true
		     north or east arrowhead
		     (depending on orientation)

	 -southwest  Whether to draw the	 true
		     south or west arrowhead
		     (depending on orientation)

       Set -parallel to false to display a point-like feature such as a polymorphism, or to indicate an important location.  If the feature start
       == end, then the glyph will draw a single arrow at the designated location:

	      ^
	      |

       Otherwise, there will be two arrows at the start and end:

	      ^ 	     ^
	      | 	     |

BUGS

       Please report them.
