hello list!!

I'm attempting to find out why this cron job isn't running. the host is centos 5.6 on i386 just so you know.

0       3       *       *       *       /bin/alldb  > /home/bluethundr/backupdb/alldb-$(date +%Y%m%d%H%S).sql

The job is meant to backup all the databases on a mysql server every day at 3 am. I have checked the backup directory and nothing is showing up for those days. 

I created the same job to run every minute but just like the job above the backups do not appear. 

*       *       *       *       * /bin/alldb  > /home/bluethundr/backupdb/alldb-$(date +%Y%m%d%H%S).sql

I have verified that the cron service is, indeed, running 

[root at VIRTCENT09:/home/bluethundr/backupdb] #service crond status
crond (pid  8053) is running...

However I do see the job is running in the cron logs

[root at VIRTCENT09:/home/bluethundr/backupdb] #tail /var/log/cron

Still nothing is appearing in the backup directory.

But if i run the command by hand it does work.

[root at VIRTCENT09:/home/bluethundr/backupdb] #/bin/alldb  > /home/bluethundr/backupdb/alldb-$(date +%Y%m%d%H%S).sql

And the file is created:
