This could be an *incredibly* stupid question, but...

    I've been asked an interesting (if somewhat bizarre) question... I wouldn't have a clue, so hopefully someone can answer it for me.

    He's running a command-line program (specifically, gnuplot) on a linux box, and he wants to be able to pipe text (commands) onto the command line of that program from the shell (in this case, bash) in another window. Is this practical, or possible? Or should I just tell him to cut and paste like the rest of us?

    Cheers,
    Gadget

    What is the purpose of him wanting to do this?

    There's a program called 'expect'

    url=http://www.die.net/doc/linux/man/man1/expect.1.html]info[/url

    It is often used for automated testing of software. It will feed commands to an interactive program using a script. Can be used with standard input as well as a file. May do the job.

    Hi:

    Thanks for the reply. I'm fully aware of expect, but it's not exactly what I want, as he wants to be able to work on the command line and pipe other stuff in (I believe this would be script-generated stuff) at irregular intervals. Thanks nonetheless.

    Cheers,

    Specifically for gnuplot, could he either
    • pipe the output of a script to a file, then use 
      load "output.txt"
      or,
    • Run the script directly, like 
      load "< script.sh"

    Not too familiar with it, but can't think of a generic way to do it.
