Auto Delete oldest files @ratex when directory is 98% full
 

I need something to delete files when the drive/partition is 98-99% full. The automatic delete needs to run regularly. Anyone have any ideas?

Maybe a script which looks at the percent used.....
num=`df -h /home |grep "/dev" | awk '{print$5}'`

If that percent is greater than some number....
if [ $num -gt some_number ]; then

Then use find to remove files which are older than a particular age....
find /home -type f -name '*.jpg' -mtime +90 -exec rm {} \;

Then put the script in a cron job to run when you want.
