Help on case to call recursively in UNIX Shell Script
Hi Vidyadhar,

Thanks for the interest shown to my query, have searched Forum and got this below script, previously i was trying to implement a case in a function try to call it again but function return once input is accomplished, I am currently using Linux ksh and will try this and let you know if there is any issue.

Code:
while true
do
    echo "Would you like to:"
    echo "1) See your name"
    echo "2) See your current directory"
    echo "3) See your home directory"
    echo "4) Quit"
    echo -n ">> "
    read case

    case "$case" in
        1) echo "username";;
        2) echo "$PWD";;
        3) echo "$HOME";;
        4) break;;
    esac
done

echo "Quit"

Thanks,
Regards,
karthikram
