in your code , you have not specified output file as CSV,
are you looping through all files inside all folders in a year?
which code is used for extracting id from file id?
You can set the output file name however you want. Replace output-file with CSV, or what ever you want the output filename to be. The find command will list all files under all directories that are of the form 2000 - 2099, so yes, in a way we are looping through all files, but letting find do the work rather than the script.
The code that extracts the ID from the name is:
The leading zeros are removed as the variable is expanded in the echo:

how you specify the coulmn names in out put file?
You made no mention of column names, only that the ID was to be first and the filename was to be second. The code prints ID followed by filename. Per your example there is no comma; I was a bit confused with your initial post as you indicated that the file was comma separated values (csv) yet you didn't indicate that the columns should be separated that way.

do you know write same logic in simple Shell, Shell Scripts?
The code I posted is a simple shell script.

if i use this loop, will it loop through all folders?
FILES=`ls -1`
for FILE in $FILES
do
Yes, but it's bad form if you ask me. Something like this would be better:

I ran your script, it says error message
[FONT=r_ansi][SIZE=2][FONT=r_ansi][SIZE=2][/work/users/po/prince]$ ./testSBI.sh
./testSBI.sh[8]: id=${id:2}: bad substitution
Were you using ksh (Korn Shell)? Bash cannot handle the last substitution which eliminates the leading zeros from the ID. If you cannot use ksh, then you'll need to change the echo and delete the zeros with sed or some other mechanism.
