I'm usually pretty good with this stuff, but my current shell script project has got me stumped. Essentially, I've created a dynamic shell menu based upon files in a single folder. It's tree-based and uses a numeric and standardised naming format:
Code:
#ls -l
total 0
-rw-r--r-- 1 root eai 0 Oct 8 08:49 011_Functionality_Example.sh
-rw-r--r-- 1 root eai 0 Oct 8 08:49 012_Another_Example.sh
-rw-r--r-- 1 root eai 0 Oct 8 08:48 01_Menu_1
-rw-r--r-- 1 root eai 0 Oct 8 08:49 021_More_Functionality.sh
-rw-r--r-- 1 root eai 0 Oct 8 08:49 02_Menu_2
-rw-r--r-- 1 root eai 0 Oct 8 08:48 0_Main_Menu
My shell script works well, but at the moment I can only provide the user with the following to assist in menu selection:
Maybe using a multidimensional array will make it easier to achieve this objective? Or you can use one array to store the names as reference to the arrays containing the menu items. The sorting and positioning problem is solved then.
Massive thanks to all three responses - I will be using a combination of your suggestions in the final version. Here's how it looks for now for anyone who may need similar:
