Hello World Day

[Nepomuk]

Hi everybody!
As was suggested here, today should be Hello World Day! So, here's my Hello World Program in bash script:

#!/bin/bash
i=0;
function hello {
	case $i in
	0)
		echo 'H'
		i=`expr $i + 1`;
		hello
		;;
	1)
		echo 'e'
		i=`expr $i + 1`;
		hello
		;;
	2)
		echo 'l'
		i=`expr $i + 1`;
		hello
		;;
	3)
		echo 'l'
		i=`expr $i + 1`;
		hello
		;;
	4)
		echo 'o'
		i=`expr $i + 1`;
		hello
		;;
	5)
		echo ' '
		i=`expr $i + 1`;
		hello
		;;
	6)
		echo 'W'
		i=`expr $i + 1`;
		hello
		;;
	7)
		echo 'o'
		i=`expr $i + 1`;
		hello
		;;
	8)
		echo 'r'
		i=`expr $i + 1`;
		hello
		;;
	9)
		echo 'l'
		i=`expr $i + 1`;
		hello
		;;
	10)
		echo 'd'
		i=`expr $i + 1`;
		hello
		;;
	11)
		echo '!'
		;;
	esac
}

hello
