> Hello. I have a logfile in which every message begins with a timestamp
(ex. - 20012091500). I would like to be able to remove the last 4 characters
(1500) off each of these to derive the date only (2001209). It works by
chopping of each character individually, but I would like to know if there
is a cleaner way to do this via regex or possibly by chopping multiple
characters off at once.
> $ts = "200212091500";
> chop ($ts);
> chop ($ts);
> chop ($ts);
> chop ($ts);

> print "$ts\n";
$ts = "200212091500";
$ts =~ s/(\d+)\d{4}/$1/;
print "$ts\n";
