jarthda has asked for the wisdom of the Perl Monks concerning the following question:

Hi, I'm trying to figure out how to make a perl script logon to a a list of windows machines and run a command.

I made this with scriptomaitc but it doesnt quite work and i dont know perl well enough to know why. 

use strict;
use Win32::OLE('in');

use constant wbemFlagReturnImmediately => 0x10;
use constant wbemFlagForwardOnly => 0x20;


my $LOG_FILE = "D:\\dops\\st.log";
open (LOG, "+>>$LOG_FILE");

my @computers = ("OHDATASTAGESF","OHSTG2SF");
foreach my $computer (@computers) {
   print "\n";
   print "==========================================\n";
   print "Computer: $computer\n";
   print "==========================================\n";
   
   my $objWMIService = Win32::OLE->GetObject("winmgmts:\\\\$computer")
+ or die "WMI connection failed.\n";
   my $colItems = $objWMIService->ExecQuery("SELECT * FROM Win32_Logon
+Session", "WQL",
                  wbemFlagReturnImmediately | wbemFlagForwardOnly);
   print LOG `schtasks /query /v`;
   foreach my $objItem (in $colItems) {
      print "AuthenticationPackage: $objItem->{AuthenticationPackage}\
+n";
      print "Caption: $objItem->{Caption}\n";
      print "Description: $objItem->{Description}\n";
      print "InstallDate: $objItem->{InstallDate}\n";
      print "LogonId: $objItem->{LogonId}\n";
      print "LogonType: $objItem->{LogonType}\n";
      print "Name: $objItem->{Name}\n";
      print "StartTime: $objItem->{StartTime}\n";
      print "Status: $objItem->{Status}\n";
      print "\n";
   }
}sub WMIDateStringToDate(strDate)
{
   return "blah ER";
}

    Looks like scriptomatic (whatever that is) is seriously b0rken (or at least doesn't work well with perl).

    For instance, that's VBScript-ish: 

       foreach my $objItem (in $colItems) {

    [download]

    That should be either (@$colItems) or (keys %$colItems) or such depending on what type of reference $colItems is. Use e.g. Data::Dumper to see what that is.

    This doesn't parse properly, either: 

    sub WMIDateStringToDate(strDate)
{
   return "blah ER";
}

    This construct looks like JavaScript. In perl, you may put subroutine prototypes in parens after a subroutine identifier, but you generally don't want to, because you don't need that. And you don't name your parameters to a sub.

    So that is 

    sub WMIDateStringToDate
{
    return "blah ER";
}

    [download]
    which, given its usefulness and no being called anywhere, you could just drop entirely.

    --shmem 

    _($_=" "x(1<<5)."?\n".q·/)Oo.  G°\        /
                              /\_¯/(q    /
----------------------------  \__(m.====·.(_("always off the crowd"))."·
");sub _{s./.($e="'Itrs `mnsgdq Gdbj O`qkdq")=~y/"-y/#-z/;$e.e && print}

      Actually not. $colItems is an Win32::OLE object and in is a function exported by that module for iterating collections.

      So ease up on the OP cos Win32::OLE is one of the hardest modules around to get to grips with even when you are fully conversant with Perl.

    That needs some work and at the moment; I don't have the time to debug it. Maybe one of the others might.

    I would suggest taking a look at our tutorials as they are very good for beginners and take a look at the Code Caverns. Click the Code link on the above left. Take a look at the NT Admin scripts and you will see a couple examples that deal with computers and checking things. I even have an old one dealing with disk space checks. You might see something you can use.

    Oh and welcome! :)
