Hi - I am using Windows 10 (latest), and Strawberry Perl (also latest). I have a perl script that is a "watchdog". It checks that a file has been updated recently (by another program), and takes action if it hasn't. If there are no exceptions, the code it runs every 15 min is below. I started this script using

psexec -d  c:\strawberry/perl/bin/wperl.exe c:\<scriptlocation>\<myscript.pl

The annoyance is that whenever it runs, a CMD window appears very briefly, and I have no idea why. I thought wperl couldn't do that.

Note: I recently switched from Activeperl (latest), because the ActivePerl libraries needed for get("webpage") were out of date (and I use this function in a different script). Point is, this annoyance did -not- happen with ActivePerl.

I can find little on the web specifically about "wperl" and that's why I'm posting - Thanks in advance for any help you can provide. /j

PS - I have a few background perl scripts running. They were dead stable in W7, but they seem to occasionally crash for not reason in W10. I understand it could be my bad coding and am working on debug, but I'm wondering if I should convert them to services (using NSSM) for stability and also for better error logging. Or would I just be taking on a whole bunch of new hurt? Thanks!!! 

while(1) {
   # timestamp the check
   $ffail=0;
   open (HC,"> $heartcheckfile") or $ffail=1;
   if ($ffail == 0) {
      print HC "$mypid\n";
      close (HC);
   }
   # check for heartbeat
   $res = check_filemod($margin+$interval,1,$heartfile);
    
   if ($res == 0) { # PH healthy 
      sleep ($interval*60); # otherwise, nothing to do but wait for ne
+xt check
   } # exception if $res !=0 omiitted as not executed
   @lines = `tasklist /FI \"IMAGENAME eq wperl.exe\"`;
   my $found=0;
   foreach $line (@lines) {
      @words = split " ",$line;
      if (($#words > 0) && ($words[0] =~ "wperl") && ($words[1] ne $my
+pid)) {
         $found=1;
      }
   } # exception if found=0 omitted as not typically executed
}
