I have set up a simple awk script to calculate the average of values that are printed out a number of times per second (the number of time the printing occurs varies). The data is of the format shown below:
Where the leftmost column is the second that the data printed out and the rightmost column contains the value. What I would like to do is to for each second, find the average of the values for that second and print out the result, then move on to the next second.
I only started using AWK a day or so again and have been trying to get my head around this. The idea behind the script below is, the sum will be calculated until no more data exists for that second, at which point the average is calculated and printed. The script will then move on to calculate the values for the next second. I have tried everything, but cannot see to get it to work.

NAME
installsieve - user utility for managing sieve scripts
SYNOPSIS
installsieve
DESCRIPTION
installsieve is a utility that allows users to manage their sieve scripts kept on the server.
OPTIONS -v <name> View script with the given name. The script if retrieved sucessfully is output to standard output.
-l List all of the scripts currently on the server. If one of the scripts is active a arrow is printed indicating that it is the active
script.
-p <port> Port to connect to. If left off this defaults to "sieve" as defined in /etc/services.
-i <file> Install a file onto the server. If a script with the same name already exists on the server it is overwritten. Upon sucessfully
putting the script on the server the script is set active. If <file> has the extension .script it is chopped when put on the server since
sieve names may not contain a '.'.
-a <name> Set <name> as the active script. The list of available names can be obtained from the '-l' option..
-d <name> Delete the sieve script on the server with <name>.
-m <mechanism> Force installsieve to use <mechanism> for authentication. If not specified the strongest authentication mechanism is chosen.
-g <name> Get the sieve script with <name> and save it to disk with a ".script" extension. If a file with that name already exists it is
overwritten.
-u <user> Userid/Authname to use for authentication; by default, the current user.
