No, it doesn't. You might want to switch to a display font that
distinguishes between a lowercase L and a number 1. If you have TrueType
support in X, I recommend Microsoft's free "Andale Mono" font for anything
monospaced; it has superb on-screen readability, and you can't mistake a
one for a lowercase L, nor a zero for an uppercase O.
Sunny: You don't need to specify -1 when the output of ls is redirected,
as it is in this case. ls defaults to one entry per line when stdout is
not a tty. Also, someone else pointed out that you can set IFS to not
break arguments on spaces; that should do the trick.
