#!/bin/bash
#
# Bash script to recursively find all content under a directory, and output
# contents plus details of contents sizes and modification time stamps to stdout
# in csv (comma delimited) format. Interactively prompts for input.
#
# Author: suuze_linux
#
# Usage: ./find2csv.sh
#
# Input from stdin. Script interactively prompts for:
#	- absolute path of top-level folder to start find search from,
#	- whether to examine hidden files and directories.
#
# Outputs the following to stdout:
#	- a single header line "File or Folder,Size (bytes),Date Modified"
#	- one comma-delimited line per inode discovered to stdout
#
# Assumptions:
#	1. Bash is available at /bin/bash
#	2. Otherwise, users default path is sufficient. This way we can run
#	   this script on any standard Unix/Linux machine.
#	3. $HOME environment variable is set to something. We do check for a
#	   valid, navigatable folder.
#
# Exit codes:
#	0 - We got through without picking up any errors. This doesn't mean we
#	    are error-free, just that we aren't aware of any.
#	1 - $INDIR is not a valid or readable directory
#	2 - $INDIR is valid but cannot parse its contents error-free
#	3 - invalid $CHKHIDDEN response
#
# Things to improve:
#	- $INDIR is tested for being an empty string. It is not tested for
# 	  being a whole lot of space, but subsequent tests should cover for it.
#	- A help option.
#	- The ability to choose the field delimiter.
#	- The ability to specify an output file.
#	- The ability to choose what 'ls' options to display.
#
# Modification history
