Ladies and Gentlemen,

Any suggestions anyone has would be greatly appreciated.

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 --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.

That's fairly basic shell syntax.  Use "double quotes" on any string where
you want variable interpolation.

        Cheers,


        Matthew
