Re: [mrtg] Perl RegEx question

Niall,
Thanks for the tip.. I think something may not be installed properly as
when I basic length("cold") I get "4SCALAR(0x8167c28)" and not just the
number 4.

When I run your line of code I get the following:

255:254:82:0:101:0:112:0:108:0:97:0:121:0:81:0:117 :0:101:0:117:0:101:0:7
6:0:101:0:110:0:103:0:116:0:104:0:32:0:32:0:32:0:3 2:0:32:0:32:0:32:0:32:
0:32:0:32:0:32:0:32:0:32:0:32:0:32:0:32:0:58:0:32: 0:53:0:48:0:13:0:10

Does this mean anythign to you?

Thanks,
Scott

I'm guessing, and may be wide of the mark.

Check your locale. I don't know enough about locale to
give any more detailed information.

Check the length of your line, and whether there are any
non-printing characters (eg NUL: 0x0) between '5' and '0',
or any unexpected characters anywhere.

Check whether the '0' is really a zero, or another character
which somehow 'looks like' a zero.

Inserting an additional line of code as follows may help with
some of the above.

my $ReplayqueueFile = <$REPLAYQUEUEFILE>; warn join(':', map { ord $_ }
( split('', $ReplayqueueFile))), "\n"; if ($ReplayqueueFile =~ m/(\d+)/)
{
