in reply to cron/perl interaction gotchas i am missing?

We would need to see the script. Many people use cron and perl w/o a problem. I use it particularly with wget with cron as well.

BTW, I've never seen the username put before the perl script.

    i can't post the whole script (passwords, IPs and overall shame), but here're the basics:
    @locations = qw/1 8 9/;

foreach $loc (@locations)
{
   $dir = getDir($store);
   $url = getUrl($store);

   chdir($dir);

   Log("starting retrieval of '$url' to file '$dir/$fn'");

   system("wget --timeout=180 $url");
}

    ...and as i said, it does finish the first wget perfectly...

      How are you sure that wget as finished and the wget process has terminated? I recommend using the logging options of wget plus adding some logging/syslog output to your Perl script as well - print statements should also be enough, as cronmails those to you.

      perl -MHTTP::Daemon -MHTTP::Response -MLWP::Simple -e ' ;    # The  
$d = new HTTP::Daemon and fork and getprint $d->url and exit;#spider
($c = $d->accept())->get_request(); $c->send_response( new   #in the
HTTP::Response(200,$_,$_,qq(Just another Perl hacker\n))); ' #  web

        because the first file (from store 1) is exactly where it's supposed to be.
        i do use basic logging in my script (see above), but after the first wget, i don't get anything....
        (and running the script manually works splendid, so i think i didn't mess up URLs and such)

      I'm guessing it's your second url that's the problem. Have you tried simply using the first url more than once to see if it's not a problem between the cron'd machine and the target?

        ...but some logging i try to do after the first wget, and before the next iteration never get done, and in a terminal it all runs fine, and the urls are completely enviroment-independant....

      XP isn't (that) important to me, but i find this curious...
