FILE_ID EXTRACTION from FILE_NAME DATE RANGE
in my first question, file_id extraction from file_name, if i need to extract file_ids in a range like January 26 2012 to today? How do I specify it?

---------- Post updated at 04:44 PM ---------- Previous update was at 04:40 PM ----------

Code:
 
!/bin/ksh
printf "file_id,file_name\n"
find 2[0-9][0-9][0-9] -name 'sasmm_fsbc_durds_id000[0-9]*_t?*.dat.trnsfr.gz' | while read path
do
        file=$(basename "$path" .trnsfr.gz)
        id=${file#sasmm_fsbc_durds_id000}
        id=${id%%_t*}
        printf "%s,%s\n" "$id" "$file"
done

I tested this solution , its working absolutely fine for file_id extraction..Thanks a lot Don..! In case , I want to extract file_id and file_name combination in a CSV file for a given date range ; for example Jan 26 2012 to today? Where do I need to make change and what would be the change?

Thanks..!
