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.
