Hi all, I'm developping a Perl script that do some system calls. Sometimes, these commands will block. I'm looking for a way to 'install' a timeout on these calls. I did some test using signals. 
$TIMEOUT = 5;
$CMD = $ARGV[0];

eval {  
   $SIG{ALARM} = sub { die "TIMEOUT\n" };
   alarm $TIMEOUT;
   
   system($CMD);
   
   alarm 0;
};
  
# do error processing

I do receive the timeout message as expected. However, the command that was started is still running in the background. How to 'kill' the command if the timeout is reached ? If using 'fork', how can I get the output of my command ? I also need the output of the command. Any suggestion ? Thanks.
