thank you..
i am new to shell scripting...
can i use iostat for getting similar result for each mount point associated with the filesystem
Alos can i change the report to show only the rate of write per hour?
---------- Post updated at 03:03 PM ---------- Previous update was at 02:50 PM ----------
also when i do df -m |awk '{print $5 " " $2}
i am getting the megabytes occupied in each of the mount point
/u02 8717924
/u01 5562586
after one hour the space is increased by few bytes
i want to get the increase in megabytes/hour for each of these mounts -- /u01, /u02
report shpould be generated every hour for one week...

If the value is preceded with a signed symbol, the filesystem is resized with respect to the current filesystem size. size can be suffixed by k,m or g to represent kilobytes, megabytes, or gigabytes respec- tively. -A device Scans the device for btrfs filesystem. -a Scans all devices present in the system for btrfs filesystem. -c Forces a filesystem sync.
