While I was cleaning the script up to make it available here, I introduced a bug. I also found a bug in my use of the expr command.
1) the cleaning bug: As I was moving the clean-up code from being scattered throughout the script to the cleanup function, I made an error during a copy and paste. As a result, the lock file is removed twice, and the temp file is not removed. 2) the expr usage bug I did not know that expr returns an error when the result of a calculation is zero. I know that now. When the script tried to refresh a table, and there were no address records to be refreshed, the script ended prematurely due to the error return code from expr. After running in production for me for over a year, only this week did this bug surface. I've put version 1.9 on my website. This version fixes both of these issues. I also put up a patch for the 1.2 -> 1.9 transition.
