Marrio woke up this morning and decided to get a present for Princess Peach. He has a file named 'given' listing all the presents he has given her in the past two months. He has another file 'desired' in which Peach listed all the presents she wanted. Toad just sent Mario another file called 'for_sale' in which Toad lists all the items he has for sale today. Each file has one item per line.
Example:
Banana Peel Red Shell Gold Mushroom
Create a series of commands to help Mario figure out what to buy Peach. The result should be a list of items which Peach wants, Toad has in stock, and which Mario has not bought her already.
As part of your research, you need to run an 'analisis.sh' script. This time, however, it's taking longer to execute than usual, and you would like to move it from the foreground to the background. What key strokes and commands should you use to make this happen?
