will this year replacement will replace any year, say the data might have 2018, 2019, 2015, 2016, so all it gotta do is extract 18, 19 and add 20 in front so the value becomes 2014,2015,2016,2017,2018, 2019. Irrespective of the year. is this possible? Also, the file is a csv so I want to pass the csv file to the awk script since the file is huge, as can be seen i had input csv file to the script
test1.csv > test2.csv

bb-csvinfo.cgi

BB-CSVINFO.CGI(1)					      General Commands Manual						 BB-CSVINFO.CGI(1)

NAME

       bb-csvinfo.cgi - CGI program to show host information from a CSV file

SYNOPSIS

       bb-csvinfo.cgi

DESCRIPTION

       bb-csvinfo.cgi  is  invoked  as	a CGI script via the bb-csvinfo.sh CGI wrapper.  Based on the parameters it receives, it searches a comma-
       separated file for the matching host, and presents the information found as a table.

       bb-csvinfo.cgi is passed a QUERY_STRING environment variable with the following parameters:

	  key (string to search for, typically hostname)
	  column (columnnumber to search - default 0)
	  db  (name of the CSV database file in $BBHOME/etc/, default hostinfo.csv)
	  delimiter (delimiter character for columns, default semi-colon)

       CSV files are easily created from e.g. spreadsheets, by exporting them in CSV format. You should have one host per  line,  with	the  first
       line  containing  the  column headings. Despite their name, the default delimiter for CSV files is the semi-colon - if you need a different
       delimiter, invoke bb-csvinfo.cgi with the "delimiter=<character>" in the query string.

Example usage
       This example shows how you can use the bb-csvinfo CGI. It assumes you have a CSV-formatted file with information about the hosts stored	as
       $BBHOME/etc/hostinfo.csv, and the hostname is in the first column of the file.

       Use with the bbgen --docurl
	      The  --docurl  option to bbgen(1) sets up all of the hostnames on your Xymon webpages to act as links to a CGI script. To invoke the
	      bb-csvinfo CGI script, run bbgen with the option

		 --docurl=/cgi-bin/bb-csvinfo.sh?db=hostinfo.csv&key=%s
