Excellent tutorial! The only problem is that I've gotten errors from the regex on three different unixes. I've quadruple-checked my syntax, so i don't think it's that.

the program I'm using with the the module is ...

#!/usr/bin/perl -w

use strict;
use lib(".");
use Uptime;

$|++;

my $uptime;

tie $uptime, 'Uptime';

printf("%20s%-20s\n", "uptime:\t",   $uptime->uptime);
printf("%20s%-20s\n", "users:\t",    $uptime->users);
printf("%20s%-20s\n", "load(1):\t",  $uptime->load('one'));
printf("%20s%-20s\n", "load(5):\t",  $uptime->load('five'));
printf("%20s%-20s\n", "load(15):\t", $uptime->load('fifteen'));
printf("%20s%-20s\n", "string:\t",   $uptime->as_string);

... and the output I get on an AIX system, a Solaris system, and a Darwin system, is ...

./dumpuptime.pl 
            uptime:     21 days,   8:02     
Use of uninitialized value in printf at ./dumpuptime.pl line 14.
             users:                         
           load(1):     1                   
           load(5):     0.04                
          load(15):     0.03                
            string:      20:39pm  up 21 days,   8:02,  1 users,  load 
+average:  0.04, 0.03, 0.04

Do I have something wrong, or is the regex in the tutoral off? Thanks, -s-

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
