Just a bit of follow-up. The '--stdout' option allows you to directly assign the
user response to a variable for many of the dialog types (menus, radioboxes,
select list, etc...) A couple of quick examples you can cut & past to test are:

Menu (returns menu text):

user_select=$(dialog --stdout --title "Most used linux command" \
--menu "Please choose from the following command line tools:" 15 55 5 \
  "man" "To read man pages" \
  "ls" "To display the contents of a directory" \
  "vi" "Text editor" \
  "mount" "To mount partitions" \
  "su"  "Super user permissions")

echo "user_select: $user_select"

RadioBox (returns exclusive index):

cpu=$(dialog --stdout --backtitle "CPU Selection" \
--radiolist "Select CPU type:" 11 40 4 \
  1 i586 off \
  2 i686 on \
  3 x86_64 off \
  4 IA64 off)

echo "cpu: $cpu"

Using an Array to hold select list options (returns all selected):

declare -a mvar

mvar=( $(dialog --stdout --checklist "Choose toppings:" 10 40 3 \
  1 Cheese on \
  2 "Tomato Sauce" on \
  3 Anchovies off) )

for ((i=0;i<${#mvar[@]};i++)); do echo "mvar[$i]: ${mvar[$i]}"; done

        I thought they were useful enough to pass along. Enjoy!
