Due 10/07!
Make me a program that tells me how many words in /usr/share/dict/words have two letters that I specify
$ sh word_count.sh a b
There are 44798 words that have 'a' and 'b'
Try our script out on a few different inputs, not just ‘a’ and ‘b’ (it should work on parts of words, too, not just single letters).
