in thread Resizing MRTG (RRDTool) logs en-masse

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
