Re: gnu tar checkpoint variable expansion

2009-10-28 Thread Jay Hall 


Try this:

/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}


The use of single quotes prohibits the expansion of environment
variables. Use double qoutes instead.


Thanks Trond, this did the trick.

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.


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

Cheers,


Matthew

I will try that again and let you know what happens.

Thanks,
