in reply to How can I close a Windows program called from a my Perl script?

Since this is Windows, you can use WMI to start,monitor, and kill the process.
use strict; use Win32::OLE qw( in ); use Win32::OLE::Variant; usage if @ARGV < 2; if( my $Pid = RemoteExec( @ARGV ) ) { print "Process created with PID $Pid\n"; } else { print "Process not created\n"; } exit; ##################################################################### sub RemoteExec { my $Machine = shift; my $CommandLine = join " ", @_; my($CLASS, $WMI, $Process, $vPid); $Machine =~ s|^[\\/]+||; $CLASS = "WinMgmts:{impersonationLevel=impersonate}!//$Machine"; print "Trying to launch @_ on $Machine\n\n"; $WMI = Win32::OLE->GetObject( $CLASS ) or die "Unable to connect to \\\\$Machine :" . Win32::OLE->Las +tError(); $Process = $WMI->Get( "Win32_Process" ) or die "Unable to get a Win32_Process :" . Win32::OLE->LastErr +or(); $vPid = Variant( VT_I4 | VT_BYREF, 0 ); # $vPid (out) PID o +f the created Process if( 0 == $Process->Create( $CommandLine, undef, undef, $vPid ) ) { return $vPid; } else { return undef; } } ##################################################################### sub usage { my($ScriptName) = $0 =~ m/.*\\(.*)$/; print<<"USAGE"; Usage : $ScriptName [\\\\]COMPUTERNAME CommandLine Parameters example :$ScriptName COMPUTER1 NOTEPAD C:\\FooBar.txt USAGE exit; }

To kill the process use kill($Pid);

    Killing the process may not be the same as closing it via its architected mechanism.

    For example, the output file may not get properly closed and flushed leading to incomplete content.


    With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'
    Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
    "Science is about questioning the status quo. Questioning authority".
    In the absence of evidence, opinion is indistinguishable from prejudice.

[Corion]: Also, I think the OPs problem is on their intranet and not on the internet (also, they should likely use WWW::Mechanize instead, which knows about cookie)
[1nickt]: yes, could be.
[1nickt]: I don;t see the link , definitely, after reloading the node
[1nickt]: Is it possible to disable it?
[Discipulus]: if you mean [download] after the code it is there 1nickt
[1nickt]: yes, Corion sees it too, and I see it when not logged in.
[Corion]: I think you can disable download links in your settings?
[1nickt]: Looking in settings to see if I disabled it in my profile ...
[1nickt]: There is "Don;t show embedded d/l links" in Display settings. It is unchecked.
[1nickt]: Oh, there is a minimum lines setting!
