In How can I process a single argument, student sends this feedback:
"""
Instructions asks to select lines 5-8 from a file. The correct answer shown is: head -n $3 $1 | tail -n $2. However this will show lines 4-8 as the tail comment will pull that last 5 lines of the 8 from head, but what you want in this case is the inclusive difference which is 4 (8-5+1). sed -n 5,8p filename would work though ;) although I'm not sure if the course gets to using sed.
