{ 
        Disk_Use=`df -h | awk '///$/{print $5}'|sed 's/%//g'` 
        TTY=`ps | awk '/bash$/{print $2}'` 
        [ "$Disk_Use" -gt "60" ] &&{ 
                echo "Date: `date` Warning:Your / is full fix it now!!" 
                sleep 2 
                Disk_Warn 
        }||{ 
                Disk_Warn 
                sleep 2 
        } 
} 
Disk_Warn
