Run from a script

PHP Code:


			
tar -czvf $BACKUP_DIR/$BACKUP_NAME *

I get the following greeting:

PHP Code:


			
tar: You may not specify more than one `-Acdtrux' or `--test-label' option

Try `tar --help' or `tar --usage' for more information.

In the script ...

PHP Code:


			
BACKUP_DIR="/mnt/disk3/backup"

BACKUP_NAME="scripts-`date +%Y%m%d`.tar.gz"
