#!/fellow/monks.pl On both AIX and Mandrake Linux, I'm experiencing a problem where programs spawned from within a perl script doesn't get killed when the parent dies. Yeah, children should live longer than their parents, but not in a perl script, I would think. Here's my code (and I've tried many different ways of opening tail).. 

#!/usr/bin/perl
open (HTML, "-|") or exec("tail","-f","testlog.txt");
print while <HTML>;

So touch testlog.txt, run the script, and start a 2nd session. Do a ps -ef and you'll see the process running, along with the spawned tail. Kill the parent, and the child becomes almost orphaned, using the inittab as it's parent. How can I kill the child when the parent dies, or at least spawn the child that it's dependant on the parent's survival?? 
[gmassyn@apt01m04 gmassyn]$ ps -ef |grep test
