Bernd, Thank you so very much!!! I would have never figured that out on my own. I went back to the Advanced Bash Scripting Guide (by Mendel Cooper) to see if this example would make a good addition. Searching on your use of Here Strings (e.g. <<<). I found on page 326 (18.1. Here Strings) a the following method that also works quite well.
read -r -a FileList <<< $(ls -1) I wish that I had noticed the Here Strings feature before. That is a great feature. Thank you both for your time and contributions!
