Shell Programming and Scripting

hi
i am writing a hangman script and am having trouble checking the correct letters against the word
i need the script to compare the word against the letters guessed that are correct so once all the letters within the word have been guessed it will alow me to create a wining senario

eg

word
hello

guessed
adhewlso

this would be a correct result because all the letters within the word have been guessed

any help would be appreciated im stumped by this

One way:

Code:

$ word=hello
$ guess=adhewlso
$ echo $word | fold -1 | sort -u | awk -v guess=$guess '{ m=match(guess,$0); if ( m == 0 ) { exit 1}}'
$ echo $?
0
$ guess=xyzhel
$ echo $word | fold -1 | sort -u | awk -v guess=$guess '{ m=match(guess,$0); if ( m == 0 ) { exit 1}}'
$ echo $?
1

unfortunatly i am not aloud to use the SED or AWK commands for this section therefore although apreciated i can not incorporate your response within my work
thankyou for your time though
