Linux command line file management

I'm a bit stuck on how to format the command to find these. The answers should go as follows: 1) 61 | 2) 108 | 3) 2

1) Answer the following questions using grep, wc, find or a combination of them. Be sure to install the dictionary /usr/share/dict/words using sudo yum install words. For every question list, the result and the command used to find the answer. There is more than one correct command for several of the questions. A. How many words start with "compu"? Hint: use grep and wc

B. How many words contain "compu"? C. What words start with "F" (capital F) and end in "ary"?
