Well, I have made a bit of headway in converting this MS-DOS batch over to bash. This seems to work from a terminal. Have yet to try it in a script. I have no doubt there's a much easier, much shorter, and more correct way to do all this but it's what I've figured out so far. There's also one problem that arises concerning the pasting to append a glue header to the logs.

Code:

::: Find all files except the current file and move to a temp dir :::
cd /home/trapper/.wine/drive_d/buzzard/logs/s-series
find . -daystart -mtime +0 -exec mv {} /home/trapper/.wine/drive_d/buzzard/temp \;

Code:

::: Paste glue header and each log file to new files in the queue :::
for i in /home/trapper/.wine/drive_d/buzzard/temp/*.log; 
do paste -s /home/trapper/.wine/drive_d/buzzard/addon.txt $i >> /home/trapper/.wine/drive_d/promail/queue/${i/.log}.101;

Code:

::: Move original log files off to archive :::
mv /home/trapper/.wine/drive_d/buzzard/temp/* /home/trapper/.wine/drive_f/archive/logs/s-series/

THE PROBLEM:
When I paste addon.txt to the log files it screws up the formatting. The files I am working with are DOS txt format. I end up with files in the queue that the MS-based mail server simply discards because they are not in the required format.

This is what the 101's need to look like:

This is what the 101's look like in windows notepad. This is what the mail server sees and rejects:
