Dynamic Bash Dialog from directory listing

Hey!

I want to get a directory listing and turn it into a bash dialog menu.
  • I need to append information from the files themselves (they'll be text files) onto the actual filenames as well.
  • I want to feed the appended filename list into the dialog menu as options.
  • I need to make a case selector that can handle the dynamic output from the dialog.

Here is the code I have so far (it does not work, at all).

Code:
#! /bin/bash

#Usage: bash Dynamic_Menu.bash /home/user/target_directory

#Section 1 - read in directory listing, store to $array[@]
i=0
while read line
do
    array[ $i ]=$i")  \"$line\""
    (( i++ ))
done < <(find $1) #consume directory path provided as argument

printf "\nInitial Array\n"
printf '%s\n' "${array[@]}"

read -rsp "Press any key to continue..." -n1 key

#Section 2 - read in file contents from array[@] files, temporarily store to $entries[@] and append to array[@]

filecount=0
for file in $array
do
	echo $filecount ": " $file
    count=0
    while IFS=";" read -r line || [[ -n "$line" ]]; do #remember to set the text delimiter
	    count=$((count + 1)); #Increment counter for menu options
	    entries[$count]=$count" \"$line\"" #Store line content into current OPTIONS array index.
    done < "$file" #this line reads the filename argument into the loop
	array[$filecount]="$array[$filecount] - $entries[1]"
	filecount= $((filecount + 1));
done

printf "\nAppended Array\n"
printf '%s\n' "${array[@]}"

read -rsp "Press any key to continue..." -n1 key

#Section 3 - Take array and feed it into a bash dialog menu as options for the user.
cmd=(dialog "Select options:" 22 76 16)
options=(${array[@]})
choices=$("${cmd[@]}" "${options[@]}" 2>&1 >/dev/tty)

#Section 4 - Create a case that can handle the dynamic output from the dialog. Not yet started


Problems:
  1. I can't get the "find" command to provide absolute paths only to the files. It also provides the parent directory.
  2. I can't get the append action to work in section section (the append)
  3. I can't get the dialog to display at all.

My text files are formatted as follows:

Filename: test1.txt
Content:

Quote:
Installed: No
The text files are contained within the directory that is fed into this script.

My desired bash dialog menu would appear as follows:

Quote:
Choose a package for installation:
1) test1.txt - Installed:Yes
2) test2.txt - Installed:No
3) test3.txt - Installed:No
Each of these files is intended to hold settings for installation and I need to track (in the text file) whether that package has been installed. The settings for the actual file installation will be labeled differently in the file and will be parsed out by the Section 4 case that doesn't yet exist.

I am developing this in Ubuntu 18.04 but intend to deploy it on TinyCore Linux with the dialog libraries installed.

I realize this is a lot to chew off at once. I haven't posted this on Stack yet because it isn't fleshed out enough and I find myself struggling.
