So are mine! Your title made me laugh, thanks. Anyway consider this code: 

my $pid = fork;
die "Can't fork!" unless defined $pid;
&do_parent_stuff if $pid != 0;
&do_kids_stuff if $pid == 0;
exit;

This is the essence of forking. The command fork creates two *almost* identical copies of the executing program. Both parent and child share everyting except the fork returns the systems process identifier (for the new child process) to the parent and 0 to the child. It returns undef if it fails. Thus by assigning the return value of fork to $pid our program can tell who it is - parent or child and behave accordingly.

Normally you would use an if/else structure and not botther with the == or != . They are the being gentle bit!

Hope this helps. There is heaps of info on fork on the site. Use super search with fork in the name and content fields
