Comparing 2 csv files and matching content
Hello,

I have the following problem:

There are two csv files

csv-file #1:
Code:
aaa1, aaa2, ... aaan
aaa1, bbb2, ... bbbn
aaa1, ccc2, ... cccn
bbb1, bbb2, ... bbbn
...
zzz1, zzz2, ... zzzn

csv-file #2:
Code:
aaa1, matchvalue1
ccc1, matchvalue2
bbb1, matchvalue3
...

Each line of csv-file #1 shall get appended the crresponding "matchvalue" of csv-file #2,
e.g. if a line contains the reference value aaa1, this line shall be appended by matchvalue1 of csv-file #2.

Finally csv-file #2 would look like this:

Code:
aaa1, aaa2, ... aaan, matchvalue1
aaa1, bbb2, ... bbbn, matchvalue1
aaa1, ccc2, ... cccn, matchvalue1
bbb1, bbb2, ... bbbn, matchvalue3
...

In csv-file #1 the "reference values" - in my example the first element of the line, may occur in more than one line.

In the example it is the first element of each line.
How would the script look like if it may be at any other particular position of the line, e.g. always the third element of each line ?

Can anyone please help me and submit a solution ?

Thanks so much !

Regards
G.

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
