Except for the formatting, how far would this get you:
Please note, that does not quite accurately describe the situation - array elements are just overwritten when indices are encountered another time(s), and awk does this as any other programming language.
Thank you so much for this RudiC. After a quick test, initial indications are that that did the trick and I can run it through a printf to take care of the formatting.
I have not seen before the "," in your variable and then "T" array. I suspect this is giving an extra coordinate to the array to make it multi-dimensional but will do more research in AWK man. I really appreciate your help.
Hello!
I am writing a program to run through two large lists of data (~300,000 rows), find where rows in one file match another, and combine them based on matching fields. Due to the large file sizes, I'm guessing AWK will be the most efficient way to do this. Overall, the input and output I'm... (5 Replies)
Hi every one;
I have a 31500-line text file upon which two following tasks are to be performed:
1: Rearranging the file
2: Taking the average of each column (considering number of zeros) and output the result into a new file
This is the code I've come up with:

join
JOIN(1) General Commands Manual JOIN(1)NAME
join - relational database operator
SYNOPSIS
join [-an] [-e s] [-o list] [-tc] file1 file2
DESCRIPTION
Join forms, on the standard output, a join of the two relations specified by the lines of file1 and file2. If file1 is `-', the standard
input is used.
File1 and file2 must be sorted in increasing ASCII collating sequence on the fields on which they are to be joined, normally the first in
each line.
There is one line in the output for each pair of lines in file1 and file2 that have identical join fields. The output line normally con-
sists of the common field, then the rest of the line from file1, then the rest of the line from file2.
Fields are normally separated by blank, tab or newline. In this case, multiple separators count as one, and leading separators are dis-
carded.
These options are recognized:
-an In addition to the normal output, produce a line for each unpairable line in file n, where n is 1 or 2.
-e s Replace empty output fields by string s.
-o list
Each output line comprises the fields specified in list, each element of which has the form n.m, where n is a file number and m is a
field number.
-tc Use character c as a separator (tab character). Every appearance of c in a line is significant.
SEE ALSO sort(1), comm(1), awk(1).
BUGS
With default field separation, the collating sequence is that of sort -b; with -t, the sequence is that of a plain sort.
The conventions of join, sort, comm, uniq, look and awk(1) are wildly incongruous.
