$1.$ Write a Bash script called a$1$a$.$sh that prints every line of one file that contains a line of a second file. That is$,$ $ $./$a$1$a$.$sh file$1$ file$2$ will print every line of file$2$ containing a line of file$1.$ As an example, suppose we have the input files $ cat foo a b bb b cc $ cat bar aa ab bc c $ cat baz ab cc ab Then the output would be $ a$1$a$.$sh foo bar aa ab bc $ a$1$a$.$sh bar foo cc $ a$1$a$.$sh foo baz ab cc ab

$2.$ Write a Bash script called a$1$b$.$sh that prints every line of one file that is not contained in a second file. That is$,$ $ $./$a$1$b$.$sh file$1$ file$2$ will print every line of file$1$ that is not in file$2.$ Using the same input files as above, $ a$1$b$.$sh foo bar bb cc $ a$1$b$.$sh bar foo aa ab bc $ a$1$b$.$sh baz foo ab ab $2$
