in reply to TTY help

Read "perldoc IPC::Run". On linux, we can use IPC::Open3 to simulate Expect, but on Win32, you need to use IPC::Run. If setup right, you can print commands to your_command, gather output, regex the output, then issue new commands accordingly.

    We don't have the IPC::Run either, but we do have IPC::Open3 but you said that won't work on windows...?
      The problem on Win32, is that Win32 dosn't support "select" on pipes. IPC::Open3 uses pipes to connect to the command, while IPC::Run uses sockets( win32 select works on sockets). BUT, if you can figure out a way to NOT use select, and get the pipes flushed, you may be able to use it. Your main problem is output may be sitting in the pipe, but without $select->can_read, you won't know it. See Pipe Problem for some ideas.

      I don't use MSwindows, but there probably are hacks to get around the problem, like using sysread to read 1 byte at a time, until nothing is there, or see Non-blocking Reads from Pipe Filehandle

      You can use the SuperSearch here for many examples of using Open3, but remember, no select is available to you... so you need a workaround. See Perl/Tk App and Interprocess Communication. If you are using an event-loop system, you can setup a timer to repeatedly read the pipe until no bytes are there. Also see " perldoc -q 'capture STDERR' "

        How difficult do you think it would be to try and work with IPC::OPen3, especially since I'm a beginner? I really need to get this done this week and its seeming impossible for me to do since I don't have alot of Perl experience. Thanks for any help, J
        Thanks I'll have a look at them. I suspect being a novice isn't gonna help me much :)
      I am also having the same problem. Any solution found, pleae share the same.
