Newbie Case Question

[Atsumi]

Hello all,

New here, and looking for assistance.

I am in need of a little help with my Linux project. We have until Friday to finish this, but since we got the assignment today, I want to turn it in tomorrow.

My teacher has decided to make us figure out case in case by our selves, or ask online since "That's what Linuxheads do." So I'm looking for someone to help me perfect this code, and maybe come up with some "fun stuff" for that category.

hi atsumi welcome to the forum.
first I would suggest you complete the code listing by adding in options and variables for the other case structures, or comment them out.
you need to make sure any scripts such as ./master exist and are found by the script.

Once this is done running the script should then start to throw up errors and broken or not understood commands / options which you can then work through.

Hope this helps

Thanks. ./master is the name of the script itself, it's calling itself back up for the main menu.

The error I'm getting most of the time when trying to run it is "Unexpected Ending", though it looks correct to me.

There are at least 3 ;;'s missing for the case statement (2 are before and after the top level option #3 and 1 after the 2nd level option #4)
and 1 done missing for the while statement.

Also I would suggest you to use select statement to display the menu. It'll make the code much cleaner. For example, your top level menu can be written as

#!/bin/bash
PS3=""
select action in  "File Operations.." "User Operations.." "Locating Information.." "Fun Stuff" "Exit" "Shut Down"
do
  case $REPLY in
    1) echo "file operations.." ;;
    2) echo "user operations.." ;;
    3) echo "location information..";;
    4) echo "fun stuff" ;;
    5) echo "exit"; exit 0 ;;
    6) echo "shut down" ;;
  esac
done
