help with hangman
i want to create the known game hangman

Code:
wordlist=./hangmanword

//hangman word is my text file which include words

i use this code to generate a random number corresponding to a word in our file
and works fine calculate and generate a right number
Code:
wordline=$( wc -l ${wordlist} | awk '{print $1}')
randmo=$( awk -v l=$wordline 'BEGIN {srand();
    r=rand()*l;
    printf("%d",( r + l ))}');

the problem is here when i want to select the appropriate word from our file
i wrote this code and appear this wrong message "awk: 2: unexpected character '.'"
Code:
word=$( awk -v l=randmo 'BEGIN {RS="";
    FS="\n"} {print $1}'$wordlist)

Finally i want a help how to replace a character who read from keyboard with -

i Forgot to write this code how to split the word to table using this code
Code:
awk -v var1=$word 'BEGIN {FS="';split (var1,T); (for i=1;i<=length(var1);i++) {print i,T[i]}}' /dev/null

i use this code to make the - - - - -
Code:
awk -v var1=$word 'BEGIN {for (i=1;i<=length(var1);i++) {printf("%s","-")};print}' /dev/null

any idea how to replace the '-' with the right character with command substr or something else
i use this code to read one character
Code:
read charact

Code:
while [ ${lifes} -gt "0" ]
do
    echo -e "\n\n You have ${lifes} remaining!"
done

if [ ${lifes} -eq "0" ]; then
    echo "GAME OVER"
    echo "The word was ${word} "
fi

i don't finish the code of while because i didn't know how to replace the '-' with the right character but the most important is to solve the error

Hi, there should be a space between ' and $wordlist

Code:
{print $1}' $wordlist

As to the ---
You means something like this?
Code:
awk -v var1=$word 'BEGIN {gsub(/./,"-",var1);print var1}' /dev/null

Alternatively:
Code:
echo $word|sed 's/./-/g'

and if you use bash or ksh you could also use:
Code:
echo ${word//?/-}

I am not sure what you mean with "the right character"

thanks friend for help

i have read many books and i read yet the last i try to study is The Complete Reference Unix" from Obserne

one thought is wrote this code to replace the '-' with right character is using the substr
is using this code to calculate the length
Code:
wordlength=${#word}
awk -v var1=$charact 'BEGIN {for (i=1;i<=wordlength;i++){A[i]=substr(var1,i,1)};for (i=1;i<=wordlength;i++){print i,T[i]}}' /dev/null

do you believe that may work or what you recommend to chance in this code to run correctly

using this code i split the word to a table

Code:
awk -v var1=$word 'BEGIN {FS="';split (var1,T); (for i=1;i<=length(var1);i++) {print i,T[i]}}' /dev/null

using this code i replace the characters with - - -
for example if the word was bedroom with this code appear - - - - - - -
Code:
awk -v var1=$word 'BEGIN {for (i=1;i<=length(var1);i++) {printf("%s","-")};print}' /dev/null

i want to read a character using this command
Code:
read charact

and if this character included for example to bedroom display this character for example

the word is :bedroom
script appear: ------- 7- depends on word length
while i read charact: press e
i want the script appear this -e----m

i think i can do that with substr

i use bash

How about:
Code:
$ word=bedroom
$ guessed=em
$ echo $word|sed "s/[^$guessed]/-/g"
-e----m
$ guessed=erm
$ echo $word|sed "s/[^$guessed]/-/g"
-e-r--m

Something like this:
Code:
guessed=""
lives=7
word=bedroom
while [ $lives -gt 0 ]
do
  read char
  if [ -n "$char" ]
  then
    lives=$((lives -1))
    guessed="$guessed$char"
  fi
  echo $word|sed "s/[^$guessed]/-/g"
done

-e-r--m

with this code the problem is that in
1st loop guessed was e
display that -e----
2nd loop when guessed was d
display that --d---
and the desire sesult was -ed----

any idea???

  fi

done

can you explain me this 2 lines what are you doing?
using this code if [ -n "$char" ] any char press the lifes decrease we want to decrease when the guessed is wrong any idea
and why use this guessed="$guessed$char"
can i ignore this line guessed="$guessed$char"
and last line wrote this echo $word|sed "s/[^$char]/-/g"


why use 2 (( here $((lives -1)) and why $ is out;
sorry for my question but i want to learn i think stupid to write somenthing don't understanding maybe i need to use many of commands in the future


In Addition the decrease must doing when i press wrong guess

---------- Post updated at 10:31 PM ---------- Previous update was at 08:28 PM ----------

one though is to split the word to a table an with for i check if char is not included to table decrease the lifes


for example in c language i can write this
for (i=1;i<=sizeof(tablep);i++)
{
if (char != tablep[i])
lives--;
}

does anyone how to make it with bash
