Answer the following questions (or at least as many as you can figure out) in this document.
|
|
For all the questions, use the 100k words. Give your answer for each exercise, and
|
|
show the command you used to get it. Each question can be answered using a single Terminal
|
|
command, though you might need to use a number of pipes.
|

|
|
|
|
`cat words_100k.txt | length | put 10 | equal | count`
