I edit script for backup:

#!/bin/sh
. /etc/profile.d/CP.sh
cd /var/CPbackup/backups
echo | backup -d --file /var/CPbackup/backups/`date`_fw_export
scp `date`_fw_export root@172.29.198.23:/data/backup
rm `date`_fw_export.tgz
exit 0

Can I exec the backup command without me being asked "Are you sure you want to proceed?"
The command "echo |" not work !!!

Thanks
