how do you set ulimit -n 5000 in perl.

How do I set "ulimit -n 5000" in perl so that it
takes affect for child processes.
I tried `ulimit -n 5000` (backtics) but a
subsequent `ulimit -n` showed the value
set back to the default.

$LIM = get_rlimits();
$lim = $LIM{RLIMIT_NOFILE};
($soft, $hard) = getrlimit($lim);

Perl doesn't have direct interface to ulimit

Another option is to set your ulimit prior to running your perl program.  Make sure you use the #!/usr/bin/perl shebang line and run perl so that it does not spawn a new shell like this:
ulimit -n 5000; ./my_perl_script_with_shebang_line.pl
