Dearest Monks,

I would like to search through all the files in a directory, and see if at least one of them is new (m-time, say). When I find one, i need to stop the depth-search.

Your thoughts will be highly appreciated! 


use strict;
use warnings;
use File::Find;

my $base = '/my/working/directory';

finddepth(\&no_old_dir_please, $base);

sub no_old_dir_please {
   return if ((-M $_) <= 30);      # how to quit finddepth on this con
+dition?
}

I know I could set a flag once i hit a new file and then just return in the sub if that flag is true. But the reason i want to stop processing is that there could 100 /1000 more files but the moment I find a new file there is no point in checking other files.

To summarize in the problem in a line: Flag the given directory as "old" if there are no new files (based on some m-time condn).

Thanks!

Update: I don't want to quit the program as I could be checking a bunch of directories like this in a loop.
