Shell Programming and Scripting

The code im having problems with is highlighted in red, upon selecting option 2 on the main menu (highlighted green) my echo "NETWORK CONNECTIVITY" command seems to get overlooked and the resulting output is "Thank you for using the Operator Administrative Tool." being displayed. Can anyone tell me how i can correct this, i want option 2 to bring up another sub-menu but for some reason it is not working even though it has been placed in the same menunumber variable.

This is really hard to read without code tags and indentation, but I'd suggest you use case statements instead of a whole bunch of nested if statements -most likely the source of your problem is bad "if" nests.

I'd go for something like this:

Code:

case ${menunumber} in
        1) do something;;
        2) do something else;;
        3) show this menu
            case ${menunumber2} in
                    1) do this;;
                    2) do that;;
            esac
         *) not a choice;;
esac

I'd suggest using ksh's "select" to built menus - it's much easier to manage.
A sample:

Code:

#!//bin/ksh

files='*sh';
actions='cat edit quit'
PS3="Pick one of the above [${actions}]: "
TMOUT=10

select i in ${actions}
do
   case $i in
      cat)  eval cat "${files}" ;;
      edit) eval ${EDITOR-vi} "${files}" ;;
      quit) break ;;
      "") print -u2 you must select one of the above [${actions}] ;;
   esac
done
