miked63017 has asked for the wisdom of the Perl Monks concerning the following question:

Hello this is my first post and I am kind of new so let me know what I am doing wrong(I am sure theres something). Basically I am writing some scripts for optical remote (across the office) drive testing. I got a simple client server setup. I would like to use threads to minimize the amount of commands I must pass through. Right now there are 6 remote machines running the server script along with some other scripts. However I do not like opening 6 client windows on the main controlling computer. I would like to open one window that gathers the ip addresses from a config file which I already have a firm grasp on. The output from the servers I would like to use threads but I dont want all of it scrolling in one window. I would like each thread to open its own window and still be able to pass data to the parent and/or server. Short version I want each thread to open in a new window. I have searched the first ten pages of google which usually can help me hack something together but not this time. I am using opensuse so linux solutions are appreciated. Thanks

    What did you write so far? What about starting with a simple, one machine controller, then expanding it? Do you have any code to show? You really don't give much meaningful detail...

      I named my script CFDeluxe for Cluster F*** Deluxe. So rather than you combing through my spaghetti code. I just need an example of threads where each thread opens in a new console although I am starting to get the feeling this is not possible
        On Linux, each console (let's say xterm to keep it simple) is an independent process, and is connected to its own pty (pseudo tty). You can open an xterm with a special command (as opposed as running a shell). If you want to display data coming from a thread to your xterm, you could use named pipes (created with mkfifo); the working thread could write to the named pipe, and the script run from the xterm would display what's coming into the named pipe.
        I don't have any code at hand for an example, but it's quite easy to do.

    What kind of "windows" do you mean? (ie. console; gui, other)?

      consoles Konsole

        Sorry, I cannot help you. I don't know if it is even possible to have multiple consoles associated with a single process under *nix.

        I know it isn't possible to do so under Windows. Multiple processes can share a console, and a process can have multiple console buffers, but each process can only be associated with a single console.

        Maybe this is a common restriction.

    I wrote this simple thread usage module several years ago - You should be able to use it to meet your requirements.

    The basic idea is that you have a work queue, workers , and a result queue.

    Feed work to the workers - they do their thing, and return results.
