Simple average: write a script that takes a list of numbers from the console (all on one line separated by spaces) and reports the average.
Text statistics: write a script that reads in a text file as one large array of words. Iterate through the array counting the total number of letters. Divide the total number of letters by the number of words to report the average word length. Also report the longest word in the text.
Movie search: write a script that reads a word from the user. The script then searches the movie titles in the file [url removed, login to view] and reports any matches. The script should also display the number of matches.
