- One of the big differences is that we didn't write out code in an IDE
but rather did it all in the terminal. The process of designing these
pipes though drew on the skills of functional programming.

- I'm used to writing these kinds of programs in a language like python
or java but it's honestly much easier to use the command line tools.

- The last exercise tripped me up because I wanted to do it in a way
that would for any word, but I wasn't sure how. Is there a way to sort
the letters in each word? My solution only works because 'sidebar'
doesn't have any repeated letters.

- Yeah, I've engaged in the group chat a bit but I don't want to flood
the chat. It's hard to gage how helpful my input actually is since we
all have differing backgrounds.

Exercises

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.

If you want to be really stylish, put your code inside of backticks like this:

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

1. What is the longest word?

cat words_100k.txt|length|order|tail -n 1|pluck 1

cat words_100k.txt|match "uu"|count

cat words_100k.txt|match "cat"|count

  • 893
