Hi siegfried,
In post #2 in this thread, I said:

Show us the source for your BackupRecords program.
In post #4 in this thread I said:
Quote:
The only thing that makes sense to me is that value returned by BackupRecords --log must return a string that includes a command substitution (from the description, probably including an invocation of the date utility) that produces different results each time $BUPLOG is expanded. But, the only way to know for sure is to see the source for BackupRecords.

I agree with the others in that the answer lies somewhere in your BackupRecords script...

If you won't show us the code for BackupRecords, it is REALLY REALLY hard for us to tell you how to fix it to do what you want.
Instead of showing us the source for your BackupRecords program as we have requested four times, you keep asking us to tell you how to fix code that you will not let us see,.

We want to help you. PLEASE HELP US HELP YOU! Please show us the source for BackupRecords! If you won't show us the source for BackupRecords, we are all wasting our time trying to help you. PLEASE HELP US HELP YOU! Show us the source for BackupRecords!

I apologize for not being more response. I've been working a lot of overtime and I did not have time to post an abbreviated version of BackupRecords.

I also apologize for not writing this little test program before posting.
This works fine.

Code:
export BUPLOG="`Date "+%Y-%b-%d-%H-%M-%S"`"
echo $BUPLOG
sleep 60
echo $BUPLOG
export BUPLOG="`Date "+%Y-%b-%d-%H-%M-%S"`"
echo $BUPLOG

This produces the desired results:
Code:
./logdemo.sh
2016-Apr-15-21-53-34
2016-Apr-15-21-53-34
2016-Apr-15-21-54-34

I thought surely bash was to blame for my multiple log files but apparently not! Bash is working exactly as I need it to...

And it actually turns out that sometimes I'm not getting multiple log files. So now I need to figure out why.

Thanks for all your help.
Siegfried
