I am trying to kill an external process called out in Perl after certain seconds.
I am using Windows.
For example, I called out "a.exe" in perl by
my $result = `a.exe`;
What should I do to kill the "a.exe" after 30 seconds before a.exe naturally ends by itself which usually takes 10mins ?
I must kill it by it's process ID but not the process name, because I will run many a.exe at the same time, and I only want the perl to kill its own a.exe. But, I have no idea how to get process ID...
Please help me. Thanks in advance!
