To clarify: You want to access an hash defined in the parent process from
all N child processes?
I'm sorry to tell you, but this won't work so easily. When forking, data is
*copied*. Which means that every child process gets a copy of all the
parent's variables, but whenever you modify them, the modification has only
an effect within the child process, because it's just a copy.
There's a whole bag full of inter process communication (IPC) algorithms,
ranging from files over sockets to posix message queues. You might to have
a look at "perldoc perlipc" and the whole lot of IPC modules on cpan.
