The following seems to do what you requested. You say that you want to create a CSV file, but by definition a CSV file has fields that are separated by commas. You don't show any commas in any of your sample output. This script uses a tab to separate output fields to get the headers to line up with the following data. Although it is written using ksh, it should also work with at least bash and sh:
Code:
#!/bin/ksh
printf "file_id\tfile_name\n"
find 2[0-9][0-9][0-9] -name 'sasmm_fsbc_durds_id000[0-9]*_t?*' | while read path
do
        file=$(basename "$path" .trnsfr.gz)
        id=${file#sasmm_fsbc_durds_id000}
        id=${id%%_t*}
        printf "%s\t%s\n" "$id" "$file"
done

Note that this will ignore any files found in and under the year directories that don't match your filename specifications.

To run it, save the above code in a file (e.g., extract) in the same directory where the year directories reside, make it executable by issuing the command:
Code:
chmod +x extract

and then issue the command:
Code:
./extract > output_file

If you leave off > output_file, the output will be written to your terminal. If you want to save the output in a file with a name other than output_file, replace it with any name you want.

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
