According to Huang Tao on 7/17/2009 9:46 AM:

I'm not sure whether it is a bug
how can i echo the text string "-e" barely ( or "-n", "-E")
i tried
$echo "-e"
$echo '-e'
and some other inputs, all of which produced no outputs.

Instead of using echo (which POSIX itself admits is fraught with
portability problems), use printf:

printf -- '-e\n'

or:
echo -n "-" ; echo "e"
