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).
Problems:
I can't get the "find" command to provide absolute paths only to the files. It also provides the parent directory.
I can't get the append action to work in section section (the append)
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.
Corona688 and RudiC - thank you both so much for your time; cannot tell you how much I appreciate it. After wrestling with this for a while I am grateful that someone would be willing to lend me some assistance. So thank you thank you!!

1) Where is the directory listing occurring in this script? I'm guessing it's at `[ -f $FN ]`
2) Can I pass an argument into this? Traditionally I've used $1, $2 etc. but I'm not intimately familiar with bash.

The simplicity of the "select" command is fantastic, and it may be the route I end up taking. I was hoping to use the Bash Dialog interface for consistency as I won't be the end user of this software. Currently I have a master menu (built statically) with common tasks. I am attempting to build this installer as a "sub" menu, or basically a bash script that gets invoked through one of the options in the main menu. A sudden change in the look & feel could confuse some users; they aren't the type that know anything about bash, linux or really much about software. Surge support we'll say.
I have the Tiny Core ncurses extensions remastered into my core file and would like to be able to use them.
But again, I appreciate all the help thus far! If an ncurses dialog is a no go then I'll give up on it. I just figured that it had to be possible...
Also, Python has been suggested but I need to keep the footprint of my OS as small as possible. My initrd is currently sitting around 13mb, compressed.

The shell will expand the * to all files in the directory. You can add a prefix of your choice, e.g test*. Then - if you're sure all selected are regular files - you may drop the -f test which safeguards you against offering e.g. directories in your select.

Does any one know how to get a recursive directory listing in long format (showing owner, group, permission etc) without listing the files contained in the directories.
The following command also shows the files but I only want to see the directories.
