It would be pretty unusual to have a file name that ends with \n, so I see that as an edge case that's probably not worth worrying about.

It's probably better to have a check after the call to RRDs::info, so I've inserted:

my $info = RRDs::info "$logsdir/$rrd"; # Check to ensure we actually have a valid rrd file unless ($info->{filename}) { print qq|"$logsdir/$rrd" doesn't appear to be a valid rrd log, + skipping\n|; next; }
Which does the trick...
$ touch foo.rrd $ ./rrd-resize.pl Starting, found 1 rrd files Processing foo.rrd "./foo.rrd" doesn't appear to be a valid rrd log, skipping Finished, processed 1 files in 0.00 seconds

    [Corion]: Yay. Traditional finance situation averted. Bonds can be quoted in amounts (1_000_000 EUR) or per unit (1 unit). And a traditional error is to trade 2_000_000 piece when you meant to trade 2_000_000 EUR.
    [Corion]: (one of my scripts simply catches high amounts and I phone people making that trade, ideally before the payment is due)
    [Corion]: The sad thing is that my script sits at the end of the pipeline and can only look at the payments due today or tomorrow basically, while there are many more systems further up in the pipeline
    [GotToBTru]: better late than never, I guess
    [Corion]: GotToBTru: Sure - there is a long and sad story of many frantic cleanups that led us to implement this notification ;)
