Unix update variable by position
Posted on 2009-02-09
Im new to Unix, as part of my learning im creating a hangman game using bash. I am having a problem showing what letters a user has guessed correctly.
So far I have 4 variables $word - that is the word a user is trying to guess, $hidden - that is the same as $word but replaces each letter with a -, $input_letter that is the current letter guess, and $position which is where the letter occurs in word.
eg $word = join
$hidden = ----
$input_letter = i
$position = 3
I want to replace 1 character in $hidden with $input_letter at $position. I also have to do this without the use of sed or awk.
Any help much appreciated
(unsure of which zone this would come under)
