Randomized Reading Lists for Kiddos using Bash Pipelines

Our kiddo is very good at memorizing stories and word sequences but needs to work on looking at the letters on the page. Simple bash pipelines can produce useful offline learning materials.

For example, print a randomized word list from inline story text for a book your kid loves:

#!/bin/bash
tr -d '",!.-' << EOF                          \
    | tr -s ' ' '\n'                          \
    | sed '/^$/d'                             \
    | sort -u                                 \
    | shuf                                    \
    | column -c 64                            \
    | nl                                      \
    | a2ps -1 --chars-per-line=70 --no-header

The night Max wore his wolf suit and made mischief of one kind
and another
his mother called him "WILD THING!"

Run the script once to produce the word list. Print the source once to have the picture-less story. Carry both in your pocket on the plane/train/etc. After some work on the word list, the kid should be encouraged by "rediscovering" the picture-less story he knows using the sight words he's just practiced. In theory. Still working on the practice.

Another example, print a randomized list of kindergarten sight words:

#!/bin/bash
sort -u <<EOF | shuf | column -c 64 | nl | a2ps -1 --chars-per-line=70 --no-header
