The UNIX Pipe Card Game

This is a card game for teaching kids how to combine unix commands
through pipes.

This game assumes the parent knows the basic unix commands: cat,
grep, tail, head, wc, sort, uniq. The parent should show also show
those commands in action the computer as well, if you do not have any
UNIX system you can use jslinux in your browser. [deck]

If you are a parent teaching your kid, and is exploring more tools to
help you, I made few other card games:

  * programming time, which is a game to teach python and some more
    fundamental algorithms, from hash tables to RSA
  * 4917, a game to teach kids machine code and how the cpu works
    with memory and registers
  * programming for kids, a log of my journey of teaching my 11yo
    daughter how to code


Example game round:

task: print the most common line from a file, we need to first cat
    the file (in our case the file is card 03.txt), then sort it,
    uniq count it, then do numeric sort, then tail -1:

    cat 03.txt | sort | uniq -c | sort -n | tail -1

[example]

RULES:

  > 0. The youngest player decides the
    objective:

  * Whoever has the smallest pipe chain to
    complete the task wins the round.
  * Whoever has the largest pipe chain to
    complete the task wins the round.

  > 1. The youngest players picks a task
    from the tasks card. You can not pick
    the same task twice.

  > 2. Shuffle the deck.

  > 3. Put the deck face down on the
    table.

  > 4. Going clockwise each player picks
    the top card from the deck.

  > 5. The player who's at turn now tries
    to complete the task.

  > 6. The first player who completes the
    task gets a point.

  > GOTO 1.
