Are we correct in assuming that each heading on the 1st line for the last 2313 fields are the single letter V followed by unique non-negative integers?
What output do you get from running the following three commands:
where file is the name of the file that contains your data.
Note that, by definition, a text file contains no lines that contain more than LINE_MAX (which is 2048 on most systems) bytes in a line (including the <newline> terminator) and most of the UNIX text processing utilities (like awk, sed, and sort) are only defined to work on text files. If the file containing your data has 2317 fields and LINE_MAX is 2048 on your system, the file containing your data is not a text file. Some versions of these utilities work even if the input files have line lengths longer than those required by the standards; other versions of these utilities will give you an error if they encounter long lines; and other versions will silently ignore some data if they encounter long lines. Hopefully, the awk script above will give us an indication of how your implementation of awk will behave. (We hope that it will just print two lines of output on standard output and not print any diagnostics.)
I have a pipe delimited file. Key is field 2, date is field 5 (as example, my real file is more complicated of course, but the KEY and DATE are accurate)
There can be duplicate rows for a key with different dates.
I need to keep only rows with latest date in this case.

In the awk below I am trying to remove all instances after a ; (semi-colon) or , (comma) in the ANN= pattern. I am using gsub
to substitute an empty string in these, so that ANN= is a single value (with only one value in it the one right after the ANN=). Thank you :).

join
JOIN(1) General Commands Manual JOIN(1)NAME
join - relational database operator
SYNOPSIS
join [ options ] 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.
-jn m Join on the mth field of file n. If n is missing, use the mth field in each file.
-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.
