if you give me 2^n pennies for the nth way i can think of doing this,
i'm gonna be loaded

0.	awk 'BEGIN{print "-n"; exit}'
1.	echo x -n | sed 's/^ //'
2.	echo print "-n\n" | hoc
3.	echo '"-n
	"' | bc
4.	unicode 2d 6e | tr -d '\012' ; echo
5.	echo '' -n | tr -d ' '
6.	'-n' = 1; whatis -n | sed 's/=.*//'
