Re: Re: How do I get the child's data?

Thanks, this looks like what I ought to do. I don't really understand
print "$$: ", int rand 0x7FFFFFFF, "\n";
Could someone explain that bit?

`print "$$: ", int rand 0x7FFFFFFF, "\n";` ...Is just some random data to show that your child process is doing something. `$$` is the process ID of a process (in this case the child process).	[reply] [d/l] [select]
