We will therefore have the spelling for some numbers in only one language, in both, or in none. None of the files are to be assumed to be already sorted by numbers. A single space is used as separator in all files. We want you to use join in order to display the following sorted lists of numbers (only numbers, not any words): All numbers that are found in digits.txt, that also have an English spelling in digits-en.txt. All numbers, that are found in digits-en.txt and digits-fr.txt, that have only a French spelling, but no English spelling. All numbers, that are found in digits-en.txt and digits-fr.txt, that have a spelling in only one of the two languages. Provide the Linux command lines to achieve these three separate objectives.
