From ff8def1c6a94c6d80718e9d25c1f42fd1c23e662 Mon Sep 17 00:00:00 2001
From: Kevin Day <Kevin@kevux.org>
Date: Tue, 25 Mar 2025 19:24:36 -0500
Subject: [PATCH] Progress: Continue working on completing the remove program.

Add UNIX Timestamp tests.
Fix date changed tests where I forgot to reset temporary date loop variable assignment before committing.

Add the accessed and updated (modified) time tests.

When recursion is disabled and a directory is being followed, then prevent a double delete by not performing the delete on the "after" at the top level.

Implement the `--prompt` support.
Make sure to take in command line input.
Make sure to quit the program when prompt is one time and the answer is no.

Change the flag to 32-bit for consistency reasons.
