He has now asked your help to create a training program for the future police inspectors. You gladly accept as you think that this will help lessen your burden of fighting crime in the future.

In a training folder, various folders `mystery` were prepared with some key differences in the data for each group of trainees.

To simplify your life as a teacher and as the answers will not be exactly the same in each `mystery` folder, you need to write a `teacher.sh` file that does the following:

- step 1, it enters the `mystery` folder.
|
||
|
|
- step 2, it isolates, thru as similar command that you used to find it, and into an environment variable, the number (**and only the number**) of the key interview that helped solved the mystery (Unlike the interview number, the adress will not change across the `mystery` folders that will be tested, hence the command to find the interview is the same across all the `mystery` folder that will be tested).
|
||
|
|
- step 3, it prints the newly created environment variable.

|
- step 4, it prints what the interview contains.

|
- step 5, it executes the command that should have printed the shorted list of 4 suspects. (it shows only the license Plate, the Make, the Color, the Owner, and the Height)
|
||
|
|
- step 6, it executes the command that should have gotten your main suspect convicted (as a reminder the result of that command should be the printing of a number) except that now you replace your suspect name with the environment variable MAIN_SUSPECT.

- step 7, step 1 to 6 are repeated for each `mystery` folder of the training folder that the program works in.

Note that for **step 2 to 6**, all the commands have to be executed with keeping in mind that the `mystery` folder is the current directory but that its name will vary.
