bash: forward_backward: command not found

Hi @s.albuqami,

The problem is that you are typing the argument after the script has finished, then when you type forward_backward, bash complains that the command does not exist.

The way you have to call your script is:

./ex3_4_script.sh forward_backward

rather than

./ex3_4_script.sh 

# script finished here

forward_backward
