Greetings all,
I'm having some trouble writing a menu drive bash script, actually coding the menu part was not difficult however its a problem with a menu option I'm having trouble with.
My menu has 5 options, when the user selects the second option, they are then prompted to enter a number from 1-9 and depending on what number they entered the following output should be displayed
Code:
1
12
123
1234
i.e. they entered 4
now this seems like this should really not be that hard, but for the life of me can't figure it out...what I have so far is:::
Code:
#!/bin/bash
echo
echo "***********************"
echo "***********************"
echo
declare stop=0
while [ $stop == 0 ]; do
cat <<ENDOFMENU
1 : the first option
2 : the second option
3 : the third option
4 : the fourth option
5 : the fifth option
ENDOFMENU
echo
echo -n " Your choice? : "
read choice
...
case $choice in
2) echo -n " Now please enter a number 1-9 : "
read number
declare i=1
while (( $i <= $number )); do
declare j=1
while (( $j <= $number )); do
echo $j
printf $j + 1
(( j++ ))
done
(( i++))
done
declare stop=1
;;
which outputs:::
Code:
1
12
23
34
41
12
23
34
41
12
23
34
41
12
23
34
4
Any help would be much appreciated.

I have an interactive menu script written in bash and I would like use PHP to open the interactive bash menu in a browser.
Is this possible?
Using the sytem() function in php runs the script but it's all garbled.
Seems like maybe a terminal window needs to be opened in php first?

tk_optionMenu(1T) Tk Built-In Commands tk_optionMenu(1T)__________________________________________________________________________________________________________________________________________________NAME
tk_optionMenu - Create an option menubutton and its menu
SYNOPSIS
tk_optionMenu w varName value ?value value ...?
_________________________________________________________________DESCRIPTION
This procedure creates an option menubutton whose name is w, plus an associated menu. Together they allow the user to select one of the
values given by the value arguments. The current value will be stored in the global variable whose name is given by varName and it will
also be displayed as the label in the option menubutton. The user can click on the menubutton to display a menu containing all of the val-
ues and thereby select a new value. Once a new value is selected, it will be stored in the variable and appear in the option menubutton.
The current value can also be changed by setting the variable.
The return value from tk_optionMenu is the name of the menu associated with w, so that the caller can change its configuration options or
manipulate it in other ways.
