Check out IPC::Run2 or IPC::Run3 (I use the latter even when I don't care about STDERR).

If you're really tricky, you can run your cli.pl with IPC::Run#, then fork off a reader that reads the STDOUT and saves to disk leaving your initial process to write to cli.pl without ever having to worry about blocking.
