Method using "bc" to first convert from Hex to Octal, the using "echo" to convert from Octal to Character.
The "cat -v" is just to avoid displaying real control codes.

Code:
while true
do
        echo "Enter Hex character: \c";read HEX
        if [ "${HEX}""X" = "X" ]
        then
                break
        fi
        HEX=`echo "${HEX}"|tr [a-z] [A-Z]`
        OCT=`echo "obase=8;ibase=16;${HEX}"|bc`
        CHAR=`echo "\0${OCT}"`
        echo "${HEX}=${CHAR}"|cat -v
done

Hex-a-hop(6)															      Hex-a-hop(6)

NAME
hex-a-hop - puzzle game based on hexagonal tiles DESCRIPTION
Hex-a-hop is a puzzle game based on hexagonal tiles. There is no time limit and no real-time element. The objective is simply to destroy all the green hexagonal tiles on each of the 100 levels. As you progress through the game, more types of tiles are introduced which make things more difficult and interesting. USAGE
You can move the character around with the keys Q,W,E,A,S,D, or with the numeric keypad. Alternatively, you can use the mouse and click on the tile you'd like to move to. Use 'U', backspace or the right mouse button to undo mistakes. The 'Esc' key (or middle mouse button) brings up a menu from which you can restart if you get stuck. Your goal is to break all the green tiles. You mainly do this by jumping on them. They will crack when you land on them, and only disinte- grate when you jump off. Try not to trap yourself! During the game, you will be given hints and instructions on what to do. Use the cursor keys or click on the arrows to scroll through the help pages. More pages will be added as you progress through the game, as new tiles will keep appearing. You can choose which level to attempt next from the map screen. Silver levels are ones you've cleared. Black levels are ones you haven't completed yet, but are available to play. There is no time limit and no real-time element, so take as long as you like. SEE ALSO
You can find more about the game on its homepage: http://www.aceinternet.co.uk/~mokona/ In Debian's version, game data is stored in the directory $HOME/.hex-a-hop/. If the environment variable $HOME is not set, it'll use /tmp/ instead. AUTHOR
