Now, it doesn't break, that is. The ssh just eats up all stdin which is redirected from .outlist.tmp, and the while read cleanly finishes on end-of-file. Did you consider using another file descriptor for redirecting its input?

SSH-ASKPASS-FULLSCREEN(1)				      General Commands Manual					 SSH-ASKPASS-FULLSCREEN(1)

NAME

       ssh-askpass-fullscreen - A simple replacement for ssh-askpass written with gtk2

SYNOPSIS

       ssh-askpass-fullscreen

DESCRIPTION

       This manual page was written for the Debian distribution because the original program does not have a manual page.

       gnome-ssh-askpass  is  a  GNOME-based passphrase dialog for use with OpenSSH. It is intended to be called by the ssh-add(1) program and not
       invoked directly.  It allows ssh-add(1) to obtain a passphrase from a user, even if not connected to a terminal (assuming that an X display
       is available).  This happens auto-matically in the case where ssh-add is invoked from one's ~/.xsession or as one of the GNOME startup pro-
       grams, for example.

       In order to be called automatically by ssh-add, ssh-askpass-fullscreen should be installed as /usr/bin/ssh-askpass

       ssh-askpass-fullscreen is a program that...

ENVIRONMENT VARIABLES

       The following environment variables are recognized:

       GNOME_SSH_ASKPASS_GRAB_SERVER
			    Causes gnome-ssh-askpass to grab the X server before asking for a passphrase.

       GNOME_SSH_ASKPASS_GRAB_POINTER
			    Causes gnome-ssh-askpass to grab the mouse pointer will be grabbed too.

       These  may have some benefit to security if you don't trust your X server. Keyboard is always grabbed.

       SEE ALSO
	      ssh-add(1), ssh-askpass(1).
