There are two possible ways on our system that a file might look that encode the date within the filename. Here are samples of each: 
 execs.000920103000
 000920_092901.nasd

I wrote the following boolean function, which I will pass to 
@todays_file = grep { -f $_ && todays_file $_ } @ftp_file_list

in order to get the files I need to ftp for today.

However, I always antsy about my regular expressions (as Jeffrey Freidl said, you can write REs to match what you want, but you also must make sure that they dont match ALL the possible things that can show up that you do not want.)

In reply to Extracting date encodings from a filename... is my regex-based function correct? by princepawn
