ENV vs BASH_ENV

Hi all,
I cannot find out the difference between defining the two variables, but I
discovered after a lot that having both set up in my crontab avoids a script
to run correctly. For instance if I have in my crontab:

ENV=/home/luca/.profile
BASH_ENV=/home/luca/.profile

then a shell script seems not to execute unless its output is redirect to a
file. So the line

00 10 * * * myBackup.sh

does not seem to run (or starts and ends immediatly), while

00 10 * * * myBackup.sh > /tmp/backup.log

works fine. If I run the backup script manually it works (it uses rsync).
What's the magic around the above variables?

Thanks,
Luca

I think that the path of the script may be an issue. When you setup
scripts in crontab its best to use absolute paths for all commands or
scripts.

Uhm...I don't believe this is the case, since the script is executed always
with a relative path, since I've set the PATH variable in the top of the cron
script.
