It's been working on RH system, but the Debian cron keeps refusing to do command
expansion on WEEK_DAY, i.e. the script produces a file named: alldb-`date +\%A`.sql
Any hint?
     

A little on the simple-minded side, but have you considered just not
using the variable?  I have a cron job that does
12 4 * * 2 /some/script | mail -s "Info for `date +'\%B \%-d, \%Y'`" [EMAIL PROTECTED]

and it has never given me any trouble.
   

Thanks, but I've got multiple crontab entries that use `date +\%A`, so it looks
better to me to assign it to a variable.
 

I would probably take your backup sequence and make a script in /etc/cron.daily

It would give you much more flexability for what you want to do.
