Hi guys i've been tryin to write a hangman game unix script and i've got a bit stuck on the hardest bits no. I'm first tryin to get a way to way to check if the inputed letter matches the other letters already inputed.

eg lets say the user has already inputed
"stored_letters=gaeop"

if they try to input "user_input=a" i need to refuse that entry since they have already entered that letter. I'm thinkin the way to do this is by cutin each letter of stored_letter and checking it aginstuser_input in a whle loop. My problem is i cant seem to write the code for this you hlp will be well appriciated.

thnx in advance
