Sounds like a job for the find command.  This

find . -mtime +30 -type f -exec rm {} \;

will delete anthing over 30 or more days old in the current directory 
and any of its subdirectories.  The '.' is the current directory but you 
can use any valid path.  The + before the 30 is needed otherwise only 
files modified exactly 30 days ago would be deleted.  The -type f means 
only files (no directories).

Do a find . mtime +30 -type f -print to just get a list of the found files.

Hope this helps,
Dan.
