Question Calculate Averages !

Hi,

I have a file with more than 2,000 rows like this:
Code:
05/26/2011,1200,1500

I would like to create a awk shell script that calculate the price average of the second and third field each 5,10 and 20 rows or ask me for the values, starting at first row.

Finally compare the average value obtained with the price of last row of the range used for the average, so know whether price is up or down.

Thanks a lot

NAME
create link - Creates a soft link and optionally specifies an expiration time and an extension time SYNOPSIS
cdscp create link link-name CDS_LinkTarget = target-name [CDS_LinkTimeout = (expiration-time extension-time)] ARGUMENTS
The full name of the soft link. The full name of the entry to which the soft link points. A date and time after which CDS checks for existence of the soft link's target and either extends or deletes the soft link. The value is specified as yyyy-mm-dd-hh:mm:ss (year- month-day-hour:minute:second). You can abbreviate this value. A period of time by which to extend the soft link's expiration time (if the server has validated that the target still exists). The value is specified as ddd-hh:mm:ss (days-hour:minute:second). You can abbreviate ths value. DESCRIPTION
The create link command creates a soft link. If you specify the CDS_LinkTimeout attribute, you must specify an expiration time and an extension time. If you omit the CDS_LinkTimeout attribute, the soft link is permanent and must be explicitly deleted. Privilege Required You must have insert permission to the directory in which you intend to create the soft link. NOTE
This command is replaced at Revision 1.1 by the dcecp command and may not be provided in future releases of DCE. EXAMPLE
The following command creates a permanent soft link named /.:/sales/tokyo/price-server that points to an object entry named /.:/sales/east/price-server. The expiration value indicates that CDS will check that the destination name /.:/sales/east/price-server still exists on June 25,1995, at 12:00 p.m. If the destination name still exists, the soft link remains in effect another 90 days. There- after, CDS will check that the destination name exists every 90 days. cdscp> create link /.:/sales/tokyo/price-server CDS_LinkTarget > = /.:/sales/east/price-server CDS_LinkTimeout =(1995-06-25-12:00:00 > = 90-00:00:00) RELATED INFORMATION
Commands: delete link(1m), list link(1m), set link(1m), show link(1m) create link(1m)
