gnu tar checkpoint variable expansion

[Jay Hall]

Ladies and Gentlemen,

I am working with gnu tar checkpoints this morning can cannot seem to  
get variables to expand properly when they are passed as part of a  
checkpoint action.  Following is how I am using gnu tar

DIR="/home/test"
WHATTOBACKUP="/home/somedir"

/usr/local/gtar-1.22/bin/tar -cf - ${WHATTOBACKUP} \
	--checkpoint-action='echo=Checkpoint #%u' --checkpoint-action='exec=/ 
usr/local/scripts/check_disk_usage.sh ${DIR}'

When I use ${DIR} as a parameter, it is not sent to the  
check_disk_usage_script.  However, if I replace ${DIR} with /home/ 
test, everything works fine.

Any suggestions anyone has would be greatly appreciated.

Thanks,


Jay
