BASH Problem / Question regarding redirection

Hi all,

Maybe someone is able to help:

Need to redirect the output of a command in realtime to a second command. Command-A executes a remote shell to another host, and outputs its results. Command-B displays a "dialog" with the outputs of Command-A.

Command-A Output:

Updating FileA
Updating FileB
Updating FileC
etc

It takes about a minute for the whole output to finish.

I've tried:

Code:

for p in `ssh user@ip.ip.ip.ip /etc/cron.hourly/command`; do dialog --infobox "$p" 3 40;done

This actually prints out the dialog, but with all the output at once. I need something that will redirect the output in realtime. So I tried:

Code:

'ssh user@ip.ip.ip.ip /etc/cron.hourly/command' | dialog --infobox "$?" 3 40

with no luck until now.

Can anyone give me a hint how to resolve this?

do_dialog

do_dialog(3alleg4)						  Allegro manual						do_dialog(3alleg4)

NAME

       do_dialog - Basic dialog manager function. Allegro game programming library.

SYNOPSIS

       #include <allegro.h>

       int do_dialog(DIALOG *dialog, int focus_obj);

DESCRIPTION

       The basic dialog manager function. This displays a dialog (an array of dialog objects, terminated by one with a NULL dialog procedure), and
       sets the input focus to the focus_obj (-1 if you don't want anything to have the focus). It interprets user input and  dispatches  messages
       as  they  are  required, until one of the dialog procedures tells it to close the dialog, at which point it returns the index of the object
       that caused it to exit, or until ESC is pressed, at which point it returns -1.
