Linux lab 4 level 4 issue

Hi, I’m currently making the lab 4 of the level 4 of Linux. I’m having this script until now:

But I’m not able to make the last dump. Don’t know why, and why the first dump run sucessfully. Also when the lab said that the use of a wildcard is needed: What the lab mean by that ? I tried with % and * when creating the user where says localhost, but in either case the scripts fails to execute. Can clarify that requirement please ?
