Shell Programming and Scripting

I am sorry if I put this wrongly.. but is the output going to give files older than 30 days or 30 days old? I am looking for older than 30 days.... Really sorry for mis-communicating.


For example: i will have files with 20121011.....dat 20120912....dat and many such months.

I want to just scp the files which are older than 30 days and scp them.

Yes it gives files older than 30 days.

for your above given formats do one thing.

for month sept and old.
Use
ls 201209* for sept.
ls 201208* for aug.
