Random

My problem is as follow and i hope you can help:

I currently have this function:

Code:

stored_word()
{
number=$RANDOM
let "number %= 21"
case $number in
0 ) echo "energy"    ;;  1 ) echo "touch" ;;
2 ) echo "climbing" ;;   3 ) echo "declare" ;;
4 ) echo "marry"  ;;     5 ) echo "relax"   ;;
6 ) echo "bugs"     ;;   7 ) echo "inaccessible" ;;
8 ) echo "country" ;;    9 ) echo "folder" ;;
10 ) echo "individual" ;; 11 ) echo "youngest" ;;
12 ) echo "disco" ;; 13 ) echo "disturbed" ;;
14 ) echo "company" ;; 15 ) echo "scientific" ;;
16 ) echo "disaster" ;; 17 ) echo "protection" ;;
18 ) echo "curiously" ;; 19 ) echo "deranging" ;;
21 ) echo "facilities"

esac
 }
then i recalled it using the Dot command suggested here into my script as follow:

Code:
        . hangman_words
        word=$(stored_word)
        letters=$(echo $word | wc -c)
        letters=$(( $letters - 1 ))
        template="$(echo $word | tr '[a-z A-Z 0-9]' '.')"
        remaining=$letters
works fine, but the words should not be in a function or hard coded... and tbh i am not what i need to do, to create a word randomly, and sed and awk are out of question as well.

Can any one shed a light on this please?

Code:
number=$(( RANDOM % 21 + 1 ))
word=$( sed -n "$number p" words_list_file )
letters=$(echo $word | wc -c)
letters=$(( $letters - 1 ))
template="$(echo $word | tr '[a-z A-Z 0-9]' '.')"
remaining=$letters

what can be used instead of sed, as i dont know anything about sed and rather learn shell scripting first and then look at sed, also just so i can understand this better, the random word file, needs to one word per line and numbered for this to work??

am i correct to assume that the above script will produce a random word, as long as the words are set as follow:

[TEXT]
word1
word2
word3
word4
etc..
[/TEXT]

You are right. Keep each word in a separate line

I have a question or two to better understand this script:

1- $str=string???
2- how dose the script compare and reads the word line?

i hope the questions are not stupid, just trying to get a better understanding.

Thx
