BASH Word Length Histogram

Following on the request for character counting in BASH, here is one that adds up the frequency of word lengths:

#!/bin/bash
for var in "$@"; do
  #echo "${#var}"
  (( Letters[${#var}]++ ))
  #echo ${Letters[${#var}]}
done
for i in ${!Letters[*]}; do
  echo $i " letters: " ${Letters[$i]}
done

And here is a sample output:

./counter.sh five six four three two one seven twenty onehundred eleven ten do a deer a female deer and that is how the cookie crumbles and i am pretty sure that you will find that this is a really useful bash script no matter how many things that you want to pass into its parameter fields
