Re:Perl system( ) command execution.

[davyy]

Hi,
Recently I started to learn Perl programming.I am using windows 7 OS. Please find the following Perl program. If I execute the below script it will show the output. The issue is that if i am executing the same script immediately again it won't execute. If I wait for5 minutes, then it executes.
I tried the same scripts in XP,it is working properly.

print "Enter the command \n";
chomp($cmd=<stdin>);
system("$cmd>ping.txt");
open($fh,"<","ping.txt") or die "could not open the file \n";
print "\n \n \n \n";
while($line=<$fh>)
 {
   if($line=~m/minimum/i)
      {
         print "Appropriate round trip time:  \n";
         print "$line \n";
       }
 }

Thanks,
Dav
