Sorry for the late reply, but you should understand that Thanksgiving time (end of November) is a good time for lots of us to now get on the computer....

I'm pretty sure I could use awk to read my file and output the information in a much better manner. Any suggestions?

Yeah, though only slightly better:

Code:

#!/usr/bin/awk -f
{
   # figure out monthsago here....
   # ...
   if (monthsago <= 0)
     bucket=0;
   else if (monthsago <= 1)
     bucket=1;
   else if (monthsago <= 2)
     bucket=2;
   else if (monthsago <= 12)
     bucket=12   
   else if (monthsago <= 36)
     bucket=36
   else 
     bucket="inf"

   sum[bucket]+=$2
   count[bucket]++;
}
END {
   for (bucket in sum) {
      print sum[bucket],count[bucket],sum[bucket]/count[bucket];
   }
}

Doing kb,mb,gb, etc is similar:

Code:

BEGIN {
  split(",kb,mb,gb,tb,xb,pb",units,","); 
}

END {
  magnitude=1;
  while (val >= 1024) { 
       val/=1024;
       magnitude++;
   }
   print val,units[magnitude];
}

Hope that helps.

IGAWK(1)							 Utility Commands							  IGAWK(1)

NAME

       igawk - gawk with include files

SYNOPSIS

       igawk [ all gawk options ] -f program-file [ -- ] file ...
       igawk [ all gawk options ] [ -- ] program-text file ...

DESCRIPTION

       Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1).

       AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like

	      @include getopt.awk

       in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path.

OPTIONS

       See gawk(1) for a full description of the AWK language and the options that gawk supports.

EXAMPLES

       cat << EOF > test.awk
       @include getopt.awk

       BEGIN {
	    while (getopt(ARGC, ARGV, "am:q") != -1)
		 ...
       }
       EOF

       igawk -f test.awk
